### 5.6.2 Air-Source Heat Pumps and 

### Integrated Appliances Present StatUs. The most efficient air-source heat pumps are the variable-speed and two-speed models. Variable-speed heat 

### pumps employ electronically oommutated motOl'S (ECM) 

### (also referred to as brushless permanent magnet motors). 

### These motors are more efficient than the 

### induction motors used in**single~spced** 

### systems. In addition. 

### the speed 

### of the ECMs can. be 

### varied to match

59system capacity more precisely to a b uildin g l oad, and thus, to im prove syst em efficiency by significantly reducing cyc ling losses. Because E CM s retain their e ffi ciency at low s( unlike indu ction motors ), energy use is also si gnifican tly reduced at low-lo ad conditions. Tw o-speed heat pumps , lik e v ari able- speed models, als o cap able of redu cing cycling losses. By employing tw o -speed induction motors to dr ive the com

pressor an d f

. Cycling l osse s = reduced because the heat pum p c an operate at a low sd to meet low buildin g lo ads. some models , two-speed compre ssors are coupled wi th v ariable-sp eed indoo r bl ow ers to i mprove sy stem efficiency furthe r. Two heat pump u rs , Carri er and Te, currently offer variable-speed h ea t pum p mode ls. er offers m odels with cooling capacities of 2 and 3 to ns . Models w ith c oolin g cap ac ities of 2.5, 3, 4, an d 5 tons are offered by T ran e. T w o-speed heat pu mp models are off ered by bo th C arrier and Lenn ox (another beat p ump manuf acture r) in 3- , 4-, an d 5 -ton c oo ling cap ac ities. EPRI and Carrier ha

The hea t pum p provided almost all water heating n eeds through the use of a tube -in-tube heat exc hang er (EPRI, 1991). Due to low sales vol umes, Carrier rem oved the HydroT ec h 2 000 from the mar ket in J anu ary 1993. The ydroTech 2 000 was offered in 2- and 3-ton c oolin g capacities. EP also co

. Nordyne cunently mar kets two different models of single-spee d inte grated beat pum ps under the Powe scr tr-ade nam e. Both m odels are offered i n 2-, 3-, and 4-ton cooling cap ac ities.

### a building load, and thus, to improve system efficiency by 

### significantly reducing cycling losses. Because ECMs retain their efficiency at low speeds (unlike 

### induction motors), energy use is also significantly reduced 

### at low-load conditions. Two-speed heat 

### pumps, like variable-speed models, 

### are also capable of reducing cycling losses. By 

### employing 

### two-speed .induction motors to drive the 

### compressor and 

### fans. the 

### system can operate at 

### two distinct capacities. Cycling losses are reduced because the heat 

### pump can operate at 

### a low speed to meet low building loads. In 

### some models 1 

### two-speed compressors are coupled with variable·speed indoor blowers to improve system efficiency further. Two heat pump manufacturers, 

# camer and Trane, cwrently offer variable-speed heat pump models. Canier offers models 

### with cooling capacities of 2 and 3 tons. Models with cooling capacities of 

### 2.5. 3, 4. and 5 tons are offered by 

### Trane.**Two~speed** 

### heat pump models are offered by both 

### Carrier and Lennox (another heat pump manufacturer) in 3-, 4-. 

### and 5-ton cooling capacities. 

### EPRl and Carrier have co-sponsored the 

### development of 

### a variable-speed integrated 

### heat pump that provides water heating 

### in addition to .space conditioning. The integrated heat pump model was marketed by Carrier under the trade 

### name HydroTech 2000. The heat pump provided almost aU water heating needs through the use of a tube-in-tube heat exchanger (EPRI. 1991). 

### Due to low sales volumes, Carrier removed the HydroTech 2000 from the market in January 1993. The HydroTech 2000 

### was offered in 2- and 3-ton cooling capacities. 

### EPRl also 

### co-sponsored the development of a single-speed integrated heat pump with 

### Nordyne Corp. Nordyne currently markets two different models of single-speed integrated heat pumps under the Powermiser trade 

### name. Both models are offered in 2-, 3-, and 4-ton cooling capacities. 

### Energy Use and 

### Cost. Efficiency ratings 

### for air-source heat pumps are 

### SEER for 

### cooling and 

### HSPF for heating. These are 

### seasonal efficiency ratings and are meant to represent more accurately the 

### seasonal perlonnanoe of the 

### heat pump. 

### Cw:rent1y the 

### DOE does not have an official test procedure for rating integrated air-source heat 

### pumps. Work has been on-going at the National Institute of Standards and Technology (NlST) to develop one. Without a speCific 

### test procedw:e for integrated systemS. 

### the individual 

### functions of the system are tested with the appropriate test procedure. The space-ronditioning performance is 

### rated in 

### accoxdanoe with the 

### DOE test 

### procedure for heat 

### pumps, while the 

### water-heating performance is 

### tested in accordance with 

### the DOE test procedure for water heaters. Table 5.13 provides the efficiency ratings. site unit 

### energy consumptions, installed costs and payback periods of various variable-speed, two-speed, and integrated heat pumps. For a discussion on the formulation of the unit energy consumptions and payback periods. 

### refer to Appendix. 5.2. For each manufacturer listed in the table, the ratings of both the high-efficiency 

### model. and the average of the entire mode! line are reported. The fourth to last column in 

### the table reportS the effiCiency ratings that were chosen to represent the 

### particular technology for this analysis. With regard to variable-speed heat pumps, the most efficient model on the 

### market was chosen as being representative for the technology. Based on discussions with

For this report one system was selected to represent each type of air-source heat pump system (i.e., one system selected for space-conditioning only equipment and another system se for integrated equipment). Based on their cost' effectiveness at providing national energy savings, the variable-speed systems were selected. Barriers to Implementation. The primary obstacle for the implementation of variable-speed and

systems is their high. installed cost. Proper servicing of the equipment also seems to be a barrier. These systems generally "loaded' with electronics and service technicians usually not knowledgeable about properly servicing them.

To obtain operating cost, the source Cs are converted to site values and multiplied by the current electricity and gas rates. The C of the base case technology, a 78% AFUE gas furn ace, is determined using the same methodology as was used for the condensin g gas furnace. The followin g equation represents the calculation necesM for determining the payback period of a gas condensing fusnace : Payback Period = (Coned F 11 Cost - Base Cwe Cost) _ (Base r Cost Cond F Opor C4sQ Conti Furn Operating Cost = (Gas Site TJEC * Gas Cost) + (Electric Sit UEC * Electricity Cost) = (43.90 MNM IU ' $6.90 tan) + (323 kWh/yr * $0.087/kWh) $331.01 Installed Cost $2690 Base Case Operating Cost = (Gas Site UEC * Gas Cost) + (Electric Sit UBC * El city Cost) (50.93 to * $6.90 tu) + (458 k yr * $0.087/k ) $391.27 Base Case In*ralled Cost = $1560 Payback Period _ ($2690 - $1560) = ($391.27 - $331.01) _ 18.75 years Thus, if advanced technology is targeted to replace only one system type, the calculation of the payback is relatively simple and straightforward. But for those advanced technologies that are targeted to replace more than one type of system, a more involved procedure is used to develop a shipment-weighted payback.

### To illustrate how a 

### payback period 

### is calculated for an advanced technology, we examine the case of a gas condensing furnace (90.5% AFUE) 

### replacing the need 

### for a standard efficiency furnace. Gas and electric source UECs were established for the 

### condensing furnace in 

### Section 3. To obtain 

### operating cost, the 

### source UECs are convened to site values and multiplied by the current electricity and 

### gas rates. The 

### UEC of 

### the base case technology, a 18% AFUE gas furnace, is determined using the same methodology 

### .as was used for the condensing gas furnace. The following equation represents the 

### calculation 

### .necessary for determining the payback period 

### of a gas condensing furnace: Payback Period :0: (Cond Fum IDstaU Cost· Base Cue JnstaU. Cost) ..;. (Base Oper Cost

### Thus. if 

### an advanced technology is 

### targeted to replace only one system type. the calculation of the 

### payback is relatively simple and straightforward. But for those advanced technologies that are targeted to replace more than one type 

### of system. a more involved procedure is used to develop a shipment-weighted payback.
