Product description:

 Water cycle household air source heat pump is one type of household heat pump. Between water tank and heat pump, the cycle liquid is water. So condenser is in heat pump, we call it double-pipe heat exchanger.

The whole Reverse Carnot Cycle is in heat pump, it consists of four component,
1. Compressor, 2. Condenser, 3. Throttle unit, 4. Evaporator

The cycle details is:
1). In compressor, refrigerant gas temp increases much.
2). In condenser. Between water and refrigerant, it’s copper pipe.
Refrigerant, gas → liquid, releases latent heat.
Water gets heat, increase temp.
3). In throttle unit. Very small parts refrigerant liquid evaporate, most part still liquid, temp drop much, more or less as temp increase in compressor.
4). In evaporator,
 Refrigerant, liquid → gas, absorb heat.
Air release heat, temp drops.
From evaporator, refrigerant gas returns compressor again, a cycle finished.

We can see from the cycle, refrigerant experienced twice state of matter change, when state of matter change, substance must get or release plenty heat. And there is a compress and expanse process, at the two processes, refrigerant temp change much, but state of matter doesn’t change.

Use electric to drive compressor work. Under hot water working mode, the main heat is not from electric, but from air. Refrigerant is heat transfer media. It transfers heat from air to water. Q1 from air + W from compressor=Q heat release to water. Normally, Q/W=4:1.
  
Water cycle household heat pump model name sample: CGKS7-400L
CG means SPRSUN brand, K means air source, S means water cycle, 7 is rated heating capacity, 400L is water tank volume.
