Constant-temperature dehumidification and refrigeration device

Abstract

The invention discloses a constant-temperature dehumidification and refrigeration device. The device comprises a compressor, a condenser, a reversing valve, a check valve I, an expansion valve, a one-way valve II, a one-way valve III, an evaporator, a heat exchanger, a temperature sensor, an outdoor unit draught fan, and an indoor unit draught fan, the output end of the compressor is connected with the input end of the condenser; the input end of the compressor is connected with the output end of the evaporator and the port S of the reversing valve; the outdoor unit draught fan is arranged outside the condenser, the output end of the outdoor unit draught fan is connected with a port D of the reversing valve, the input end of the one-way valve I is connected with a port C of the reversing valve, and the output end of the one-way valve I is connected with the input end of the expansion valve and the output end of the one-way valve III. According to the invention, equipment is simplified,the number of expansion valves is reduced, and the technical effect that on the basis of the conventional refrigeration dehumidification function, constant-temperature dehumidification can be conducted easily at a low cost is achieved.

Description

technical field [0001] The invention relates to the field of a constant temperature dehumidification and refrigeration device, in particular to a constant temperature dehumidification and refrigeration device. Background technique [0002] Air-conditioning systems are used in various occasions. The air-conditioning systems used in computer rooms, data centers and other occasions will be described below. [0003] With the rapid development of big data, computer room air conditioners have also entered an era of rapid development and response. There are various electronic devices in the computer room. To improve the stability and reliability of these devices, it is necessary to strictly control the temperature and humidity parameters of the environment within the specified range. Early computer room air conditioners used comfort air conditioners, which often caused problems such as unstable operation of computer room equipment, static electricity, and condensation due to impro...

AI Technical Summary

Problems solved by technology

At this time, if the computer room needs to be dehumidified, the dehumidification capacity is limited due to the short running time of the compressor, and the humidity in the computer room cannot be controlled at this time.

In this regard, traditional precision air conditioner manufacturers generally use electric heating for thermal compensation. After using electric heating, the running time of the compressor can be increased and the dehumidification capacity can be increased. However, the increased heat of several kilowatts of motor heats the air unevenly and requires additional air conditioning equipment. capacity, increasing electric heating is not the most economical form
