Heating and heat recovery unit for an air conditioning system

Abstract

A heating and heat recovery unit for an air conditioning system, which is assembled from compressors, several insulated water storage tanks, an air-cooled condenser, expansion valves, air-cooled evaporators and a water-cooled evaporator. The compressors are suitable for various types of air conditioning systems and refrigerant heat pump water heater systems. The installed water storage tanks are arranged according to size, from the largest at the top down to the smallest at the bottom. A high-temperature and high-pressure refrigerant from the compressors is first input into the smallest tank, and after passing through to the largest tank, it is then passed on to the expansion valve and the evaporator. A configuration of cold water pipes is provided for input into the largest tank through to the smallest tank 50 , and output therefrom. Hence, the heat exchange flow process consists of heating of cold water after entering from a cold water inlet end, and heating the water before output at a hot water outlet end, moreover, each of the tanks can be independently heated to raise the temperature thereof.

1 . A heating and heat recovery unit for an air conditioning system, comprising:
 at least one compressor;   at least one insulated water storage tank for heating and heat retaining use, the insulated water storage tanks are internally configured with heat exchangers; a high-temperature and high-pressure end refrigerant compressed by the compressors passes through the heat exchangers to effect heat exchange with water, and the heat is stored within the insulated water storage tanks;   an air-cooled condenser; after the temperature reaches a set value, then surplus heat is dissipated through the air-cooled condenser;   at least one expansion valve connected to the air-cooled condenser;   at least one air-cooled evaporator; heat dissipated from the air-cooled condenser passes through the expansion valve to the air-cooled evaporator, where evaporation takes place, and the refrigerant is returned to the compressors.
