Abstract

The invention provides a heat reclamation module unit, which comprises a compressor, a first four-way valve, a second four-way valve, an air-conditioning water shell-tube heat exchanger, a first throttling device, a second throttling device, a third throttling device, a first heat exchanger, a hot water shell-tube heat exchanger, an air-liquid separator, a liquid storage tank and a connecting pipe; the D end of the first four-way valve is connected with the exhaust end of the compressor; the E end of the first four-way valve is connected with the output end of the air-conditioning water shell-tube heat exchanger; the S end of the first four-way valve is connected with the input end of the air-liquid separator; the C end of the first four-way valve is connected with the D end of the second four-way valve; the C end of the second four-way valve is connected with the input end of the first heat exchanger; the E end of the second four-way valve is connected with the output end of the hot water shell-tube heat exchanger; and the S end of the second four-way valve is connected with the input end of the air-liquid separator.

Description

technical field [0001] The invention relates to the field of heat exchange, in particular to an air conditioning unit, a heat recovery module unit and a control method for the operation of the heat recovery module unit. Background technique [0002] Common heat recovery units on the market use the same throttling device for heating and hot water, which cannot achieve optimal matching of heating and hot water. [0003] In addition, the heating heat recovery mode of the heat recovery unit of most manufacturers can only give priority to hot water heating or heating priority, and cannot be selected according to the customer's operating needs, resulting in the unit not being able to fully meet the customer's requirements. When the multi-module unit is running, each unit in the module can only operate for heating or hot water in a unified manner. When switching between heating and hot water, the valves in the system switch directly, and the system fluctuates greatly. When the un...
