Heat recovery

HISEER heat recovery chiller /heat pump

Normal air cooled chiller moves heat from indoor to outside air . HISEER heat recovery chiller /heat pump moves heat from indoor to domestic hot water. It not only cools your house , but also provide free domestic hot water.

 

Working principle

 

 

Heat recovery/chillersCooling + free domestic hot water mode

 

1) Domestic hot water is cold, DHW pump ③ is switched on. High pressure and high temperature hot gas compressed by compressor is condensing in DHW heat exchanger ②, the refrigerant is cooled and releases its heat energy to DHW. The refrigerant’s temperature drops and condenses to a liquid state.
DHW inside tank ④ is heated up. fan motor ⑤ is off, condensed liquid out of finned coil exchanger ⑪ is expanded in expansion valve ⑥ and become low pressure ,lower temperature liquid and evaporates in air conditioning heat exchanger ⑦, A/C pump ⑨ is switched on,the cold liquid refrigerant is heated up by the A/C water and evaporates into gas.Fan coil unit ⑧ brings cool air to cool the house. Evaporated gas is sucked by compressor and compressed again to another cycle.

On this stage, it works like a water to water chiller.
 

2) Temp of domestic hot water inside tank ④. rises to 45℃, fan motor ⑤ is switched on and draws the outdoor air through the finned coil heat exchanger ? to cool down refrigerant.

3) Domestic hot water temp. rises to pre-set temperature, DHW pump ③ is switched off. Hot discharge gas is condensing inside finned coil heat exchanger ⑪ instead of DHW heat exchanger ②. On this stage, it works like a normal air cooled chiller.

Hot water mode

 

DHW pump ③ is switched on, A/C pump ⑨ is switched off. 4 way valve changes direction.

Refrigerant condenses in DHW heat exchanger ② and evaporates in finned coil heat exchanger ⑪ , just like a normal hot water heat pump.
