Heat recovery triple generation system

Abstract

The invention discloses a heat recovery triple generation system which comprises a heat pump compressor, a heat recovery device, a liquid storage tank, heat exchangers and a gas-liquid separator. An outlet of the heat pump compressor is connected with an inlet of the liquid storage tank through a pipeline, and the heat recovery device is mounted on the pipeline. An outlet of the liquid storage tank is connected with the input end of an electromagnetic valve A and the input end of an electromagnetic valve B through pipelines, the output end of the electromagnetic valve B is connected with inlets of the heat exchangers and an inlet of the gas-liquid separator, and an outlet of the gas-liquid separator is connected with an inlet of the heat pump compressor through a pipeline. The number of the heat exchangers is two, the output ends of the two heat exchangers are each connected with a one-way valve, the two one-way valves are connected through a pipeline, and the pipeline between the two one-way valves is connected with the output end of the electromagnetic valve A. The heat recovery triple generation system is reasonable in design, good in gas-liquid separation effect, small in system fluorine injection quantity and good in environment friendliness, machine overloading is avoided, and the service life is long.

Description

technical field [0001] The invention relates to the technical field of domestic and commercial heat recovery, in particular to a heat recovery triple supply system. Background technique [0002] The heat released by the unit through the condenser is usually discharged to the surrounding environment by the cooling tower or cooling fan. It is a huge waste for places that need heat, such as hotels, factories, hospitals, etc., and it also brings a certain amount of waste heat to the surrounding environment. pollute. [0003] Heat recovery is to recover and reuse a large amount of waste heat discharged to the outside during the operation of the chiller in a certain way, as the final heat source or primary heat source for the user. According to the amount of heat recovered by the heat recovery device, heat recovery can be divided into partial heat recovery and full heat recovery. Among them, partial heat recovery can only recover part of the heat discharged by the chiller, and t...

AI Technical Summary

Problems solved by technology

[0004] The existing heat recovery system has a large amount of fluorine injection, which will pollute the air

When the water temperature is too low, the air conditioning effect is not good; when the water temperature is high, the pressure is too high, the machine load is too heavy, and the service life is affected
