He said that was the best it would do until the aux. Heat pump is not suitable for cooling with water temperature under condensing temperature e.g. I stand by my post from Oct 28. bivalent operation of electric heat pump with electroboiler (integrated in one device) balance point according to heat output (dimensioning) acc. I finally turned my heating system on this evening. You may need to extrapolate to be accurate within the body of the table (for example, if you have an entering air temperature of 73F, and the table only provides for 70F or 75F). A compact ground source heat pump with a heating output of 5.8 to 10.4 kW and a cylinder capacity of 220 litres. These calculators offer various variables and it is a good idea to try them all to get a good idea of what is involved in calculating heat pump requirements. I have a question though about the heat strips. heated timber … And when it's in aux heat mode, the discharge air temp should be at least 100-110 degrees. High Temperature Heat Pumps ft; 4 ton … An increase in the input temperature (T cold ) means, for example, an oversized ground source of heat. ft; 3 ton - 1500 sq. If your ductwork is correct, it provides enough insulation and should not be a concern. The unit was 5.5 years old, just outside of warranty. Instead of generating higher-temperature heat in intermittent blasts, heat pumps generate lower-temperature heat continuously. It worked great over the summer. In normal case the high-temp side should be at least in the high 90's. These were bench tests, forcing the compressor and interior heads to different ranges, but it's indicative of the range to expect in normal modulating operation. Also my out put temp is 80-84 degrees when room is at 68. Well, it's been almost a week and the Trane field rep never got the sheet and now he's on vacation until Dec. 1. I am all electric and have to have both. it does depend on the distance from register to the strips, where the ducts travel and the temp of the area where the ducts are. Using that theory it would take an extraordinary period of time to reach 70 degrees, which would be unexceptable to any home owner that I know. I called technicians. Inside thermostat was set at 65...real inside temp was 63. "Effective" down to -13 doesn't mean efficient. Discharge air temps for ductless mini-splits can easily exceed 120F in some cases. If you don’t have a heat pump, and your conventional system is not working normally, go to the Troubleshoot strange heating or cooling behavior article for more help. Now less us consider the same room at 50degF and you set the thermostat to call for 70degF. I don't really know that much about HVAC design. It is 25* outside right now and the air temp out of register is 82* with a room temp of 71*. Don't take that brushoff for an answer. Something is wrong here. The old unit was a 10 seer, the new one is a carrier that is 13 seer. Today's new heat pumps produce heat at or very near a person's body temp(without heat strips). THE OUTPUT TEMPERATURE AT THE VENT CLOSEST TO THE HANDLER IS 78 DEGREES WITH JUST THE PUMP RUNNING. Your installer should verify the charge in the heat pump and the compressor. You are also in a more humid area than what they test them in. I'm just worried why he had to fill it. He came out to the house, filled in the sheet and spent another 2 hours tinkering. 2 ton - 1000 sq. We live in Northern Ireland with a reasonable winter climate not often below7degrees C. The kitchen will be open plan. At -9,7F running flat-out it was delivering 88F air. My Fujitsu mini-splits, set at 68 F, kept my house at 68 F last night, when the low temp was -6 F and the night before, when it dropped to -4 and didn't get above +6 all day. The optimal heat pump temperature range is above 25-30 degrees Fahrenheit. Clay, Example - Maximum Heat Pump Efficiency. To me it seems this unit is not working properly, mainly the aux system. Return air temp is 70 degress and the supply is only 79-80 degrees at the vent closest to the unit. 150°C or above) for industrial uses (while maintaining reasonable efficiency) Ground source heat pump for cooling; Industry case studies. I have set the temp differential to 6 degrees to prevent the aux heat from coming on. But whether my thermostat is set at 60, 65 or 70, the air coming out is only 72 degrees. with a thermastat setting of 69deg., the heat pump is running almost constantly,(maybe off for 1/2 hour during an 8 hr. Those who choose air to air, not so much. The temperature range was 90-93F. I presume I'm losing heat in the slab/ductwork but how do I quantify how much? Let’s consider one of our standard model of heat pump Thermagen2X 8028A. Would appreciate any light you can shed on this aspect. Alibaba.com offers you an exclusive collection of heat pump temperature output that not only conserve energy for you but also serve the purpose of heating proficiently. It was 99 degrees outside. I keep my house on 68 winter and summer. Is the air usually only 10 degrees warmer than what the thermostat is set at? Vancouver BC is seeing summers with 30 C. I rent a 50's "hot box" that hits 29 C by 9pm (yes...it keeps getting warmer after the sun goes down...awesome insulation...not). Most of the time the output will be warmer than 110F. When I did so, the outside temperature was 41 deg. I HEAR THAT THE OUTPUT TEM SHOULD BE MORE IN THE AREA OF 90 DEG OR SO. Outside temp was 38 this morning. No, air from a heat pump won't be as warm as with a gas or oil system, but as MacQ notes, there's NO way it should be that chill. However, as temperatures start dropping, output starts dropping as well – and when output starts dropping, the heat pump will “work harder” to keep your home at temperature. Aux heat was indicated to be on. Return air thermometer in return air rectangularduct about 6 feet from furnace intake.Outdoor air temperature = 42*FReturn air Temperature = 68*FTemperature at Register = 92*FDelta T = 92 - 68 = 24*F. Calculated Quantities. I set the therostat at 75. Trane's field service rep sent a data sheet to my hvac guy to fill out and the field service guy will troubleshoot the problems.Regarding the ductwork...when I insulated up in the attic all appears normal. We would not have any other boiler. When the temps drop below 40 it barely keeps up and when it drops below 30 the temperature in the house drops about 5-6 degrees. With all ductwork in conditioned space and return air temp at 70F, a standard heat pump with air handler set at ~400cfm/ton will have discharge air temperature of about 97F at … I HAVE A 2.0 TON TRANE XR13 HEAT PUMP. I have been putting in heat pumps for 30 years in cold climates. period). Once it was replaced, the unit worked fine. Its not a set temperature like the other guy just responded to you. Heat Pump Calculators The objective of using a heat pump calculator is to determine the size, cost and eventual cost savings of the heat pump system you will need based on your heating requirements. TigerDunes...I am, I am. Heat pumps are rated for “output.” In this example, when it is 30 degrees out, a heat pump will easily produce 100% of its output at the highest efficiency. In the summer, a heat pump acts just like an air conditioner and has similar energy output and Can anyone provide a description of what should be happening so that I can discuss it with the tech? Pure High Temperature Heat Pumps are available from 30kW to 1,500kW utilising both Low Global Warming Potential (GWP) HFO and Natural refrigerants. Your design temperature is probably -15, and it gets much colder than that. It uses thermocouples just downstream from the blower in the supply plenum; the blower runs continuously at very low speed (around 300 rpm) until the heat pump cycles on. © 2021 The Taunton Press, Inc. All rights reserved. (60 °C at type HP) However, efficiency is worse at this temperature (COPdecreases). More and more people in the "temperate" lower mainland are finding summers are getting harder and harder to live through without AC. The maximum theoretical efficiency can be calculated by using (1b) as COPheating = (40 + 273) / ((40 + 273) - (-5 + 273)) = 6.95 The temperature fell only after 7:00 p.m. Heat pump is not suitable for cooling with water temperature under condensing temperature e.g. See 2020 update here Summary of a brief presentation at the Ground Source Heat Pump Expo at the Ricoh Arena on the topic ‘Energy or Performance Monitoring’, so its timely to do a little blog here to elaborate … Continue reading Heat Pump Performance Monitoring Examples I thought they really couldn't do the heating job and need a backup system when the outside temperature got below 32 degrees. (CO2 & Hydrocarbon) At this temperature condition, the heat pump delivers 28.15 kW of thermal output. Using Them to … So, if your house temp was 50 degrees (burrrr) then the heat pump might only produce air that is 72 degrees. An air-source heat pump releases air that's in the 90 to 100 degree range. To everyone with properly working heat pumps...I'm jealous. home in S.C. Thermostat set at 69 degrees and being maintained by heat pump(Rheem RPMD 12 Seer, 8.2 HSPF, 3 ton unit with scroll compressor)with NO AUXILIARY heat being called for. Even in a hot summer day, our heat pump had to only start 3 Backup heat for mini-splits? It puts out 85-95F, more when the strips are on. Heat pumps are rated by AHRI for heat output at two outdoor temperatures, 47°F and 17°F. Again, you should be getting supply air temp in the 90s. Suitable cooling system cooling ceiling, Clay, I have had a Fujitsu ductless minisplit for about 3 years and I had a conventional, ducted heat pump before that. You can also see heating cycles of Sanitary water and Cooling water in the 24h period. Never seen a temperature differential on a A/C unit nor a heat pump, maybe different terminology. Then, factor in the snow and how you intend to keep it far enough away from the outside unit all winter so that it has at least some chance to perform well in temperatures above 0. Anything colder than 72* in the room and I feel very cold because the air from the heatpump is not like other means of heating. the customer mentioned it is a high eff system, so even if it is a large strip pack, they will be computer controlled, to keep the temp rise low to save $$$if the heat strips are large, then the temp rise will be higher, when the strips kick in. At some point, the temperature of the home’s heating requirement and the heat pump output match. This feature has been temporarily disabled during the beta site preview. The first night, I stopped in between jobs at around 7:30 PM, interior temp was about 63Â°F. At cooling mode is output water temperature limited to condensing temperature. Therefore, reducing the output temperature (T hot) is very efficient, but requires very efficient heat transfer from heat pump system to surroundings (i.e. As the outdoor temperature drops, the heating requirement of the house increases and the output of the heat pump decreases. Low temperature water causes condensation on inner equipment of indoor unit and thereby the damage. A "hot day" was 29C and that happened once/year. With all due respect to the naysayers on this thread, your heat pump is not functioning like it should. and air distribution. Well, it's been in the 30s for the past two days here in Ohio and I can tell you the heat strips have only kicked in when the unit defrosted.

At cooling mode is output water temperature limited to condensing temperature. The indoor return air temperature rating point is 70°F. Was mostly curious about the additional bump from the heat strips. We also turn the unit off during the day when at work. But a heat pump only lives up to its full potential in terms of performance and sustainability when it converts waste heat from industrial production, exhaust air from air-conditioning systems, or waste heat from chillers and then makes it available as heat output at a higher temperature level. In the summer, a heat pump acts just like an air conditioner and has similar energy output and efficiency based on the model you choose. I was wondering why you would only expect her to get a few degrees of extra temp rise with them. Last year, Nov/Dec 05, my son with a Trane heat pump began to have problems - failing to heat. The total volume of the room is: If we desire 3 air exhanges per hour we must then move all the air in the room 3 times per hour or 800 x 3 = 2400cuft of air/hr. I have the same unit, 1.5yrs old. thanks gang. You should easily be receiving an air temp in the low to mid 90s. Has anyone had experience of this either good or bad. Room temp is 72*. Airflow through the ducts appears good, which IMO implies good sealing. Somewhere around 22* it will not be able to maintain the thermostat setting and the aux heat will kick on. Heat Pump Calculator 1. Heating and cooling duct systems are typically designed to provide two to three compete air exchanges per hourtherefore when designing the duct system you must begin by computing the total volume of the room in question. High Temperature Heat Pumps provide output temperatures in excess of 55C with a maximum output flow temperature of 120C. Ignoring supplemental electric resistance heat for a moment...with standard heat pumps the colder the outdoor temperature, the colder the discharge temperature on the inside. Heat recovery to 70Â°F triggers at 12 AM. Something is wrong with your unit. Heat Pump – How does it work Heat Pump, Refrigerator, Air Conditioner – basic principle of operation. How to Get the Necessary Field Test Numbers. Your heat pump's output is based on the temp of the air in the house - that is - its intake air. Tomorrow it's supposed to get to 27 degrees as the low so I expect the auxiliary heat to be activiated. F., and the emergency/backup heat coils were NOT on. There were no tears and everything seemed firmly affixed. The maximum theoretical efficiency can … Room temp is going down because the H.P is not able to keep up with the outside temp. immediatly before and after the air handler. The discharge temperature on ANY heat pump system is going to vary with the outdoor temperature. We like to sleep cold so turn the unit off at night. So even though there’s no single ideal temperature, you do want a 16°–22° F difference from the supply air and return air. The temperature your AC puts out is relative to the temperature you set on your thermostat. I have a little experience with heat pumps and gas furnaces, and have always noticed the difference in temperature of the air coming through the registers. When the room is cold, is it more economical to let the unit to run constantly by keeping set point max at 6 degrees or go ahead and let aux kick in and get temp up faster? Passive Solar Cabin wiith Heat Pump at 46 N Latitude. Btu is a unit of energy used to measure heating and cooling systems, as such, a heating or cooling … He checked outside and he said I was slightly low on the r410a, and he filled it back, and I then had 95 degree heat out of my vents. I got home at 1:45 AM, the unit was still running, inside temp up to ~68Â°F. Theheating seasonal performance factor (HSPF) is a measure of the total heat output in Btu of a heat pump over I also forgot to mention I'm on a slab. He didn't sound too alarmed and I got the air from a heat pump is never as warm as natural gas lecture. It is still considered mandatory to light the large wood stove if the temperature will get below 0. Thanks. He said he would fax over the data sheet to Trane right away. My sister has a 15-20 year old unit that is putting out 100 degree air. The heat pump is very efficient when the outside temperature is around 45 degrees Fahrenheit to 50 degrees Fahrenheit, but it becomes less efficient as the temperature drops. You may have to get the address from your Trane Dealer. vstech, Thanks much for bringing clarity to this thread. Thanks to John S. and Dana D. for your detailed and helpful responses. 1 Btu = 1 055.05585 joules. duing the second 20 minute period the 60 degF air again enters the HVAC unit and is heated an additional 10degF. I think this is the same for the ducted systems. Any one telling you different is lying to you. The best way to check the aux heat is to start with cold ducts so that any residual heat … Below 30* it runs continually without aux heat kicking in. Disregard last post....I replied to the wrong thread..DUH!! The first few minutes I get the typical blast of 66 degrees and then maybe, maybe, it gets up to 73 or so. If your heating system is properly sized and properly ducted regardless of what type of heating system you have the output air should never be more than 10 to 15degF warmer than the room air. In the experimental range used, the cooling output, Q output, and COP increased with an increase in the temperature of regeneration heat source. I turned my system on for the heating season about 2 months ago, and it wasn't doing a good job of heating. The maximum cooling output of 3.12 kW was achieved under the operation conditions of T eva,in / T con,in / T hot,in = 287/303/353 K and θ a/d = 300 s. If your heat pump is not keeping you comfortable in your home, contact your licensed professional HVAC dealer for an inspection to determine a solution for your heating or cooling concerns. Maxed out is maxed out. So I was under the assumption the next time it would kick on, 80 degree air would come out. Heat pump is indeed running longer to maintain set point... 15 minutes on 5 minutes off which indicates to me that I'm not too far off from the balance point at which auxiliary heat would be needed. Terms. My father has a 10 year old 12 seer Trane that is putting out 95 degree air. From this post I see that the customer is keeping his home at a very low temp. fancoil. Heat pump temperature output is based on several factors, the outside temp is one of the most important. Even on really cold days, your discharge air temperature should be quite a bit more than 72 degrees. You must be a magazine subscriber to access this feature. Had a cool snap down here for a few days last week. Since a Btu is a measure of heat, a dropping supply temperature goes hand-in-hand with the output of the HP. This is not a rip off, it is the going rate for AC. he stated the house is set at 65 and room temp is at 63, when the system comes on. A heat pump drawing heat from a ThermalBank at 25°C can provide very effective heating to an underfloor heating circuit designed to operate at 35°C. • Temperature. Hopefully this article has helped answer that question, and any others about heat pump temperature ranges, and what you can do to improve heat pump performance when it gets below 25-30 degrees.

First: The air temp coming out of the registers is not a function of your thermostat. Again, he said it wasn't that low, but that's what the problem was. of house is 69 deg. Spring comes a month earlier and summer lasts a month longer. THE FIRST FOUR OR SO YEARS IT OPERATED PROPERLY. I just had my 13 year old carrier unit replaced. The output in Btu's and also the temperature of the output will be dependent on how much heat the outdoor unit can absorb in an hour. If your installer tries to feed you that line again, tell him to shove it in his pipe and come out and find out why your newly installed system isn't working the way it's supposed to. After opening and closing my exterior doors (it was 30 degrees that day) the aux. If your heat pump is not cooling, it may be one of a few problems, most of which are similar to those listed above. The opposite for a cooling process - a lower cold temperature will increase the efficiency. During cooling it should reduce the intake air temp 20+ degrees and during heating should raise it a similar amount. I hope there isn't a small leak as it shouldn't drop at all in 3 years, right? They say a heat pump is good for heat in temperature down to 20 Fahrenheit, but I have had them for years, recently replacing old with newer and very high efficiency, and it's still the same temperature range. and explained the air coming out is only 72 degrees. Heat Pump – How does it work Heat Pump, Refrigerator, Air Conditioner – basic principle of operation The term heat pump is usually reserved for a device that can heat a house in winter by using an electric motor that does work W to take heat Q cold from the outside at low temperature and delivers heat Q hot to the warmer inside of the house. Final Thoughts: At What Temperature is a Heat Pump Not Effective? e.g. For a given heating load, the control logic on the ductless units tends to err on the side of better occupant comfort (higher temp. Air conditioner or heat pump operating temperature diagnostic questions & answers: HVAC system temperature FAQs: Questions & answers about air conditioner or heat pump system temperatures at the equipment, at the cooling or heating coil, at the supply or return registers, & how those temperatures help diagnose HVAC system problems. I live in a climate with four distinct seasons and cold winters. During the first 20 minute period the air enters the heating unit at 50degF and is heated 10degF, thus the temperature at the duct will be 50+10=60degF. If you’re not sure you have a heat pump, start with step 1. If a heating system is improperly sized so that it blasts out hot air at greater than the 10 to 15 degf differntial you end up with severe stratification and drafts in the house. So the fact that your fan is set for 1600 CFM for stage 2 is correct. When the outside temperature is 43 degrees and inside temp. Keep the pump on the “cool” setting at 78 F (26 C) for the best efficiency. Suppose you have a temperature requirement of 80°C and your ambient temperature is 20°C. Last night, we dipped to about 14F, and my 3T packaged heatpump was set at 69F, but the thermostat showed RT of 63F. Never approaching the balmy 80 degree mark. Furnace discharge air temperature can be well over 120F as well. I read somewhere that heat pump air temps are usually 95* where gas furnaces get the air temp up to 115*. Heat pumps extract heat from the air and move it, efficiently creating a comfortable space regardless of the outdoor temperature. The maximum cooling output of 3.12 kW was achieved under the operation conditions of T eva,in / T con,in / T hot,in = 287/303/353 K and θ a/d = 300 s. Take your thermometer out and you should have 20 degrees Fahrenheit differential between … Anywhere from 15 to 40 degree diff. Q hot = COP heating x W = 3 x 1500 = 4500 W or 4500 J/s In case of the cooling mode, the heat pump (air conditioner) with 1500 W motor can take heat Q cold from inside the house and then dump Q hot = 4500 W to the hot outside. The purpose is to insure an adequate circulation of the air during the heating or cooling cycle. I get 75 at the nearest register, some are around 72 and I have one that never breaks 69. It's in good working order. The air temp at the registers finally made it to 90 degrees. With a variable speed compressor and variable speed air handler heat pump system (such as a ductless mini-split), the discharge temperature is going to vary a lot...based on outdoor temperature, compressor speed and air handler speed. 60 + 10= 70degF. Things to keep in mind. The heat pump is mostly used for cooling and only for heating down to around 35 degrees Fahrenheit, any colder than that and it becomes ineffective and the electric furnace switches on. could be normal depending on the system.
