Direct contact type hygrostat based on compressor frequency control and method thereof

Abstract

The invention discloses a direct contact type hygrostat based on compressor frequency control and a method thereof. The hygrostat comprises a cabinet, a fan, a compressor, a condenser, a water tank, a throttle valve, an electromagnetic reversing valve, a frequency converter and an evaporator. The compressor, the condenser, the electromagnetic reversing valve, the throttle valve and the evaporator are connected sequentially; the evaporator is arranged in the water tank, the air inlet of the fan is communicated with outside through a fresh air pipe, the air outlet of the fan is connected to a spraying pipe, and the spraying pipe is inserted into the bottom of the water tank from the right of the water tank; the top of the water tank is provided with a guide plate, and the air outlet of the top is provided with an air blowing pipe. According to the hygrostat, the water temperature is adjusted through the refrigerating capacity of the compressor, and the air dehumidification is changed by controlling the water temperature; the system further adopts the electromagnetic reversing valve, when air humidification is required, the system operates in a manner of a heat pump, the water temperature rises, and humidification is performed conveniently; the hygrostat is compact in structure and is specially adaptive to constant humid environment of a large showcase or antique storeroom.

Description

technical field [0001] The invention relates to the field of energy air conditioners, in particular to a direct contact constant humidity device and method thereof using frequency conversion control of a compressor. Background technique [0002] The display of cultural relics requires a specific temperature and humidity environment, which is generally obtained through a constant temperature and humidity air conditioning system. In most cases, compared with the temperature, controlling the humidity of the environment is more important to the protection of cultural relics. If a constant temperature and humidity air conditioner is used for control, the cost is too high and the energy consumption is large. In order to achieve dehumidification and humidification functions, the constant humidity device is usually equipped with dehumidification and humidification devices at the same time: dehumidification generally adopts cooling dehumidification, that is, the air exchanges heat wi...

Problems solved by technology

Therefore, the system is more complex and more difficult to control

In terms of control, the constant humidity devices on the market use the start-stop control of compressors and fans, the system cannot run continuously, and it is difficult to achieve precise control of humidity, and the frequent start-stop of the system is also prone to failure
