Modular air cooled heat pump hot water unit

Abstract

The invention discloses a modular air cooled heat pump hot water unit. A first four-way reversing valve (2) is respectively communicated with a compressor (1), a second four-way reversing valve (3) and a hot water side shell and tube heat exchanger (6), the second four-way reversing valve (3) is respectively communicated with an outdoor heat exchanger (4), the compressor (1) and an indoor heat exchanger (5), the indoor heat exchanger (5) is communicated with the outdoor heat exchanger (4) through a first check valve (7) and a first electronic expansion valve (10), the hot water side shell and tube heat exchanger (6) is communicated with a first electronic expansion valve (10) through a second check valve (8), the second check valve (8) is communicated with the indoor heat exchanger (5) through a second electronic expansion valve, and the outdoor heat exchanger (4) is communicated with a second electronic expansion valve (11) through a third check valve (9). The modular air cooled heat pump hot water unit combines an air conditioning system with a hot water system so as to lower the running cost, the modular air cooled heat pump hot water unit is effective, energy saving and low in noise, harmful gas emission and environment pollution are avoided, and the space is saved.

Description

technical field [0001] The invention relates to the field of air conditioning, in particular to a modular air-cooled heat pump water heater unit. Background technique [0002] At present, offices, hotels, hospitals, restaurants and other places that use air-conditioning units also need to use domestic hot water, but generally the air-conditioning system and the hot water system are completely separated, and the simultaneous operation of the two independent systems requires high energy consumption and operational management costs. Moreover, many occasions such as hotels and group dormitories have high requirements on noise and surrounding environment, and it is not allowed to install boilers, or it is not easy to install cooling towers and other hot water equipment. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a modular air-cooled heat pump that integrates the air conditioning system and the hot water system to...
