Specific embodiment
The utility model is further described with reference to the accompanying drawings and examples.
As shown in Figure 1.
One kind can air-cooled cold (heat) the water dispenser group of low temperature total heat recovery, refrigerant circulation circuit constitute it is as follows:
The exhaust outlet of compressor 18 connects the first interface of air conditioning water heat exchanger 4 after the DE of four-way reversing valve I1 mouth；Institute
The D mouth of the C mouth connection four-way reversing valve II2 of four-way reversing valve I1 is stated, the S mouth of four-way reversing valve I1 is after gas-liquid separator 16
Connect the air entry of the compressor 18.
The first interface of the C mouth connection air-side heat exchanger 3 of the four-way reversing valve II2, the E of four-way reversing valve II2
The first interface of mouth connection hot water heat exchanger 15；The S mouth of four-way reversing valve II2 connects the gas-liquid point after check valve IV17
Import from device 17.The check valve IV can close the circuit of air-side heat exchanger, prevent refrigerant migration from major loop being caused to lack cold
Matchmaker, while guaranteeing that the sliding block in two four-way valves can kill on valve seat, prevent refrigerant low pressure reverse leakage.This is unidirectional
Valve IV can also use solenoid valve.
After the second interface of the air conditioning water heat exchanger 4 is sequentially connected filter II7 and the second orifice union, and successively connect

The electromagnetic valve component includes solenoid valve 13 and check valve III12 connected with each other.
Between 15 second interface of hot water heat exchanger and the electromagnetic valve component and connect a compensator 14.
The specific working mode of the utility model is as follows:
1. when refrigeration, four-way reversing valve I and four-way reversing valve II power down simultaneously, refrigerant circulation route are as follows: compressor --
-- DC mouth --- air-side heat exchanger --- the filter I--- check valve I--- of four-way reversing valve II is saved the DC mouth of four-way reversing valve I
Stream unit II--- filter II--- air conditioning water heat exchanger --- ES mouth --- gas-liquid separator --- compressor of four-way reversing valve I
Gas returning port.
2. when heating, four-way reversing valve I is powered, four-way reversing valve II power down, refrigerant circulation route are as follows: compressor ---
DE mouth --- air conditioning water heat exchanger --- filter II--- check valve II--- throttle part I--- filter of four-way reversing valve I
I--- air-side heat exchanger --- --- press the CD mouth of four-way reversing valve II by the CS mouth ----gas-liquid separator --- of four-way reversing valve I
Contracting machine gas returning port.
3. when recuperation of heat, four-way reversing valve I power down, four-way reversing valve II is powered, refrigerant circulation route are as follows: compression
Machine -- the DC mouth of four-way reversing valve I -- DE mouth --- hot water heat exchanger --- check valve III--- filter of four-way reversing valve II
