Problems solved by technology

[0011] Three heat exchangers and two solenoid valves on the refrigerant side are used to close the refrigerant passage of the heat exchanger when the multi-function switch is realized; the defects are as follows: the air side heat exchanger has a large refrigerant side cavity , so if it is closed by the liquid solenoid valve after the function is switched, and is connected in parallel with another condenser; the c

Abstract

The invention relates to a water source heating-air conditioning-hot water three-way set. The asymmetric phase change rate with magnitude difference among parallel heat exchangers is formed by switching on and switching off the driving force of a refrigerating medium side and matching the guiding of a check valve of a refrigerant side to radically replace an electromagnetic valve switch refrigerant loop; and five functions of heating, air conditioning, hot water, air conditioning and hot water (an ordinary type/an energy saving type), and the like are realized in a mode of simpler structure, lower cost, more reliable operation and higher efficiency. The water source heating-air conditioning-hot water three-way set accords with a natural law of 'Dujiang Dam' action through inaction, radically eliminates hidden trouble of lack of fluorine of heat exchanger operation caused by stopping using refrigerant fluid stored in the heat exchanges in the prior three-way set, and is favorable for home application of products.

Description

(1) Technical field [0001] The invention relates to a three-purpose machine for water heating, air conditioning and hot water. (2) Background technology [0002] The obtained Chinese invention patent "heating / air conditioning + hot water machine" (patent number: ZL200410038964.1), [0003] 1. One electric three-way valve is required for the water circuit, and two solenoid valves are required for the refrigerant circuit, so that the initial investment of the system is reduced and the control is simplified; [0004] 2. In summer, spring and autumn, winter, and severe cold, respectively: refrigeration / heat pump-air conditioning + hot water cycle, gas-water heat pump hot water cycle, gas-water heat pump heating cycle, refrigeration-air conditioning cycle, 4 optimized operation modes to meet heating requirements The three functional requirements of air conditioner and hot water enable it to operate throughout the year, and the operating efficiency is always the highest. The init...
