Problems solved by technology

[0003] Among the 3 heat exchangers of the heat pump, the 2 air-side heat exchangers and the hot water heat exchangers connected in parallel are only switched by 2 refrigerant liquid circuit solenoid valves, and the refrigerant gas circuits are completely connected, so that During the multi-function switching operation process and when the heat pump is shut down, it is impossible to control the series flow and accumulation of refrigerant between the two parallel heat exchangers, so that the running heat pump circuit sometimes lacks refrigerant and sometimes has excessive refrigerant, resulting in unstable operation and even protection.
For example, because the air side heat exchanger has a large refrigerant cavity, if the liquid circuit of th

Abstract

An air source heating air conditioning hot water machine adopts the combination of only two refrigerant electromagnetic valves and one refrigerant check valve to solve the hidden danger in the prior art of an air source three-way set that as a changed-over heat exchanger stores refrigerant liquid constantly through six to eight refrigerant electromagnetic valves, fluorine shortage in a heat pump cycle is aggravated gradually, fundamentally avoids the refrigerant circulation between the changed-over heat exchanger and the heat pump cycle, and realizes the long-term self-stabilization operation, therefore, the air source heating air conditioning hot water machine is endowed with the four functions of heating, air conditioning, hot water supply as well as air conditioning together with hot water supply through simpler structure, lower cost, more reliable operation and improved efficiency.

Description

(1) Technical field [0001] The invention relates to an air source heating air conditioning water heater. (2) Background technology [0002] The obtained Chinese invention patent "heating / air conditioning + hot water machine" (patent number: ZL200410038964.1), a heat pump circuit composed of 3 heat exchangers and 2 solenoid valves, realizes the three functions of heating, air conditioning and hot water Comprehensive utilization; the investment + operation cost at the beginning of 20 years of operation is 20-45% lower than that of the existing technology. However, the system has the following serious problems in actual operation: [0003] Among the 3 heat exchangers of the heat pump, the 2 air-side heat exchangers and the hot water heat exchangers connected in parallel are only switched by 2 refrigerant liquid circuit solenoid valves, and the refrigerant gas circuits are completely connected, so that During the multi-function switching operation process and when the heat pum...
