Valve control type energy-saving dehumidifier

Abstract

The invention relates to a valve control type energy-saving dehumidifier comprising a shell and a refrigerating system, wherein the refrigerating system consists of a compressor, an evaporator, a condenser and an expansion valve, wherein the condenser comprises an inner condenser and an outer condenser; an air inlet of the inner condenser is communicated with an air outlet of the evaporator; the inner condenser and the outer condenser are respectively connected with the expansion valve through two-way filters; the inner condenser and the outer condenser are connected with a four-way valve (9) through reversing valves; one end of the compressor is connected with the four-way valve (9), and the other end thereof is connected with the four-way valve (9) through a gas-liquid separator; one end of the evaporator is connected with the expansion valve, and the other end thereof is connected with the four-way valve (9). The valve control type energy-saving dehumidifier not only has a dehumidification function, but also sufficiently utilizes refrigerating output and heat which are generated in the system, and can realize the effects of all-year dehumidification, summer (or high-temperature state) refrigeration and winter heating, thereby greatly reducing the energy consumption.

Description

(1) Technical field [0001] The invention relates to a valve-controlled energy-saving dehumidifier. (2) Background technology [0002] The dehumidifiers used in daily life are usually refrigeration dehumidifiers, which do not have the function of room temperature adjustment. Like air conditioners, they have a refrigeration system consisting of a compressor, an evaporator, a condenser and an expansion valve. In this system, the The compressor converts electrical energy into mechanical energy, generates high temperature and high pressure, causes the refrigerant to boil in the condenser, releases a large amount of heat energy, and completes the liquefaction of the refrigerant. Evaporation in the state, absorbing a large amount of heat energy, completing the vaporization of the refrigerant and returning to the compressor, completing the cycle of high temperature and high pressure-exothermic liquefaction-filtration and decompression-low temperature and low pressure-evaporation, he...

Problems solved by technology

[0003] The above-mentioned dehumidification process must rely on a high-temperature and high-pressure condenser, a low-temperature and low-pressure evaporator, one generates high temperature, and the other produces low temperature. The two energy sources of cold and heat are also needed in our daily life and industrial and agricultural production. , if the two energy sources cannot be well regulated and utilized, it will be a great waste
