Dehumidifier with air volume regulation function

Abstract

The invention discloses a dehumidifier with an air volume regulation function. The dehumidifier comprises a compression vapor refrigeration cycle part, an air volume regulation part and a control part, wherein the compression vapor refrigeration cycle part is composed of a compressor, a condenser, an expansion valve and an evaporator circularly connected by a pipeline in sequence; the compression vapor refrigeration cycle part is filled with a refrigerant; the air volume regulation part comprises an air duct, an air door, an execution device for opening and closing the air door, and a fan; the control part comprises a temperature sensor and an integrated circuit board. The dehumidifier provided by the invention adopts an air volume regulation method to reduce the air volume flowing through the evaporator and increase the air volume flowing the condenser at high temperatures, so that an effect of reducing the degree of superheat and reducing the high pressure of a system is achieved, the reliability of the dehumidifier working in high temperature conditions is improved effectively, and the dehumidifier can dehumidify a dehumidifying space within a wider range of ambient temperatures.

Description

technical field [0001] The invention relates to the field of refrigeration dehumidifiers, in particular to a dehumidifier with air volume adjustment. Background technique [0002] A humid environment is not conducive to people's activities, and is also not conducive to the storage and use of equipment and instruments. The function of a dehumidifier is to dry the air and make people or equipment work in a suitable environment. The evaporator is used to obtain a temperature lower than the dew point of the ambient air by using the compressed vapor circulation refrigeration system. When the air flows through the evaporator, the temperature drops and the moisture in the air is condensed, and then the air passes through the condenser, which raises the temperature of the air. Higher, the relative humidity in the air decreases. The working range of the dehumidifier in the traditional compressed vapor refrigeration system is narrow, and usually only works within the range of 18-38°C...

AI Technical Summary

Problems solved by technology

The working range of the dehumidifier in the traditional compressed vapor refrigeration system is narrow, and usually only works within the range of 18-38°C. In wet and cold environments and high-temperature and high-humidity environments, it is prone to shutdown protection and other phenomena, mainly because of the working pressure of the refrigeration system. caused by too high or too low
