Description

Technical Field

[0001] The utility model relates to the field of direct expansion air conditioning units, in particular to a constant temperature and humidity unit with variable frequency condensation heat recovery and disinfection and purification. Background Art

[0002] To put it simply, the concept of a direct expansion air-conditioning unit is that the unit itself has a compressor. The liquid refrigerant in its refrigeration system evaporates directly in its evaporator coil to absorb heat from the air outside the coil and cool it. Direct expansion air-conditioning units include various forms of air-conditioning products, such as unit-type air conditioners, ceiling air conditioners, and suspended ceiling air conditioners.

[0003] According to the published patent 202121230076.5, a reheat heat return DC variable frequency energy-saving constant temperature and humidity direct expansion air-conditioning unit includes a device body, a hood and a fan. The top of the device body is fixedly connected to the hood, and the bottom of the hood is embedded with a fan. A heat dissipation socket is connected through one side of the fan, and a copper pipe joint is fixedly connected to the bottom of the heat dissipation socket. A circulation mechanism is composed of an evaporator, an expansion valve, a compressor, and a condenser. When the air-conditioning unit is activated, the liquid refrigerant in the evaporator absorbs the heat from the air and begins to evaporate. Eventually, a certain temperature difference is formed between the refrigerant and the air, and the liquid refrigerant also completely evaporates and becomes a gas, which is then sucked in and compressed by the compressor. The gaseous refrigerant absorbs heat through the condenser and condenses into liquid. After throttling through the expansion valve, it becomes a low-temperature and low-pressure refrigerant and enters the evaporator, completing the process. In the process of realizing the present utility model, the inventor found that at least the following problems in the prior art have not been solved: when the air conditioning unit is activated, the liquid refrigerant in the evaporator absorbs the heat of the air and begins to evaporate, and finally a certain temperature difference is formed between the refrigerant and the air, and the liquid refrigerant also completely evaporates and becomes gaseous, and then is sucked and compressed by the compressor. The gaseous refrigerant absorbs heat through the condenser and condenses into liquid, and then becomes low-temperature and low-pressure refrigerant after throttling through the expansion valve and enters the evaporator to complete the cold cycle process. However, during use, the traditional variable frequency condensation heat recovery constant temperature and humidity unit will produce more gas and liquid extraction and transportation. During the gas and liquid extraction and transportation process, the gas and liquid will be attached with impurities and bacteria, which will affect the use effect of the direct expansion air conditioning unit. For this reason, it is necessary to design a new technical solution to solve it. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, meet actual needs, and provide a constant temperature and humidity unit with variable frequency condensation heat recovery and disinfection and purification, so as to solve the technical problem that the current traditional constant temperature and humidity unit with variable frequency condensation heat recovery will produce more gas and liquid extraction and transportation, and in the process of gas and liquid extraction and transportation, the gas and liquid will be attached with impurities and bacteria, which will affect the use effect of the direct expansion air-conditioning unit.

Since the plurality of liquid filter screens 202 are arranged in the disinfection and purification box 203, when the expansion valve 208 inputs the condensed water into the evaporator 205, it will be disinfected. The multiple liquid filter screens 202 inside the purification box 203 are purified and filtered, thereby avoiding the presence of impurity particles in the condensed water that affects the subsequent evaporation effect. Moreover, when the liquid filter screen 202 needs to be replaced, the first handle 201 can be directly grasped to extract different liquid filter screens 202, and the liquid filter screen 202 can be easily replaced, which solves the technical problem that the traditional variable frequency condensation heat recovery constant temperature and humidity unit will generate more gas and liquid extraction and transportation.
