Non-blind zone temperature regulating dehumidifying machine

Abstract

This invention relates to a kind of non-blind area temperature-controlling dehumidifier. It includes centrifuging fan, air cooled condenser, evaporator, expansion valve, first one-way valve, liquid storage and water cooled condenser. It also includes the second one-way valve and refrigerants three-way proportional valve. The second one-way valve is arranged between the input port of liquid storage and output port of water cooled condenser; the three ports of the refrigerants three-way proportional valve are respectively connect to input port of air cooled condenser, output port of compressor and input port of water cooled condenser. The air cooled condenser and water cooled condenser are parallel connected through refrigerants three-way proportional valve. This invention can realize air output temperature continually adjustment within 16.6-38.5DEG C. The pipeline is simplified and the fault points are reduced. Thus it increases controlling accuracy and operation reliability. As the water -flow regulating valve is not needed, the cooling water system is simplified. The water resistance and power dissipation of water pump are reduced too.

Description

1. Technical field [0001] The invention relates to a temperature-regulating dehumidifier, in particular to a temperature-regulating dehumidifier with continuously adjustable outlet air temperature and no temperature-regulating dead zone. 2. Background technology [0002] Ordinary temperature-adjusting dehumidifiers integrate the functions of temperature-rising dehumidification, temperature-regulating dehumidification and cooling dehumidification, and have been widely used in occasions where the heat-humidity ratio varies widely (such as national defense projects, civil air defense projects that combine peacetime and wartime). The use situation shows that the existing common temperature-adjusting dehumidifier also has the following problems: [0003] (1) There is a blind area in the temperature adjustment range, so that some projects that require control of a wide range of outlet air temperature cannot be well controlled without additional auxiliary equipment. A large number...

AI Technical Summary

Problems solved by technology

[0015] Under the condition of temperature regulation, the outlet air temperature of the CTZ dehumidifier can only be reduced to about 26°C, while under the full water cooling condition without the air-cooled condenser, the outlet air temperature of the CTZ dehumidifier can be reduced to 16°C. That is to say, there is a blind area of ​​10 °C in the adjustment range of the air supply temperature of this type of dehumidifier, which is very unfavorable to the control of room temperature. If the required air supply temperature is just in the blind area, it will inevitably cause dehumidifier operation. Frequent switching of the environment, the room temperature will also fluctuate greatly

[0016] (2) The existing ordinary temperature-adjusting dehumidifier has the problem of mismatching refrigerants in various working conditions, resulting in high system pressure in the heating condition of the unit and low system pressure in the cooling condition

At the same time, due to the adoption of two condensers in series, the resistance of the refrigeration system is large, which also has a certain impact on the dehumidification effect.

[0017] The applicant's utility model patent No. ZL992300762 discloses a temperature-regulating dehumidifier, which consists of a centrifugal fan, an air-cooled condenser, an evaporator, an expansion valve, a pressure relay, a water-cooled condenser, a needle valve, a refrigeration compressor, Composed of a refrigeration solenoid valve, a liquid receiver, a one-way valve and two solenoid valves, a heat pipe heat exchanger is installed between the evaporator and the air-cooled condenser. This temperature-adjusting dehumidifier can improve the dehumidification effect and consume less energy. low, but there is still a temperature regulation blind spot; the applicant’s utility model patent No. ZL992300754 discloses a series air-cooled temperature regulation dehumidifier, its structure is similar to that of the utility model patent No. ZL992300762, but there are also Temperature regulation dead zone
