Auxiliary heat-dissipating device by cooling water of refrigerator

Abstract

The invention discloses an auxiliary heat-dissipating device by cooling water of a refrigerator connected between an air conditioning unit and a main pipeline of cooling water of the refrigerator. Themain pipeline of cooling water of the refrigerator is a pipeline between a condenser of a cooling water unit and a cooling tower. The auxiliary heat-dissipating device comprises a heat transfer assembly, a PLC control cabinet and a water pump assembly, wherein the water pump assembly is connected to the main pipeline of cooling water of the refrigerator, one end of the heat transfer assembly is connected to the water pump assembly while the other end of the heat transfer assembly is connected to a water supply end of the air conditioning unit, and a water return end of the air conditioning unit is connected to the main pipeline of cooling water of the refrigerator. The invention provides the auxiliary heat-dissipating device by cooling water of the refrigerator. By taking the heat transfer assembly as a bridge, heat of high-temperature cooling water generated by the cooling water unit is transferred to reheated hot water of an air conditioner in a summer mode, and after the high-temperature cooling water is cooled, the burden of the cooling tower is alleviated, so that the energy efficiency ratio of the cooling water unit is further improved.

Description

technical field [0001] The invention relates to the technical field of supporting equipment for clean workshops, in particular to an auxiliary heat dissipation device for cooling water of a refrigerator. Background technique [0002] Air conditioners are generally installed in clean workshops such as automobiles, electronics, and pharmaceutical industries. Due to the large space in the workshop, the workload of the air conditioner is also large, so the following problems will arise: [0003] Status 1: Humidity in Huangmei before summer, cooling tower heat dissipation efficiency drops a lot, resulting in higher outlet water temperature and increased energy consumption of chillers; dehumidification capacity of air-conditioning system decreases, and humidity in clean room exceeds standard. [0004] Status 2: After the dehumidification of the clean room purification air conditioning system, the temperature of the air supply air is low. In order to avoid the clean room from being...

AI Technical Summary

Problems solved by technology

[0003] Situation 1: Humidity is high in Huangmei before summer, and the heat dissipation efficiency of the cooling tower drops a lot, which leads to an increase in the outlet water temperature of the chiller and an increase in energy consumption; the dehumidification capacity of the air conditioning system decreases, and the humidity in the clean room exceeds the standard

[0004] Status 2: After the dehumidification of the clean room purification air conditioning system, the temperature of the air supply air is low. In order to avoid the clean room from being too low, a large amount of heat source needs to be consumed (the northern cities often provide steam in November, so electric heating has to be used) Airflow for heating

The air supplied by the air conditioner is first cooled and dehumidified and then heated, which causes the problem of wasting energy due to "cold and heat offset"

[0005] Status 3: The condenser of the chiller has a large heat dissipation, and the cooling tower, cooling water pump and chiller cooling water main pipeline system that need to be equipped consume a lot of electricity
