Adjustable energy-saving type constant temperature and humidity machine unit

Abstract

The invention relates to an adjustable and energy-saving constant temperature and humidity unit, comprising a frequency converting type compressor, an evaporator, an expansion valve, a steam adjustable humidifier, a single pipe adjustable heater, a condenser and a centrifugal fan, wherein, the frequency converting type compressor is connected with the condenser; the condenser is connected with the thermal expansion valve; the thermal expansion valve is connected with the evaporator; the evaporator is connected with the frequency converting type compressor; and the single pipe adjustable heater, the steam adjustable humidifier and the centrifugal fan are connected with the evaporator. The technical effect of the invention is that: after adopting the frequency converting type compressor, the power of the compressor can be adjusted by frequency converting, leading to protect the compressor and save large amount of energy. After the single pipe adjustable heater is adopted, the energy consumption arising from excess heat quantities and big temperature fluctuation are avoided. The steam adjustable humidifier utilized can avoid the energy consumption and big ambient humidity fluctuation.

Description

technical field [0001] The invention relates to a constant temperature and humidity unit, in particular to an adjustable energy-saving constant temperature and humidity unit. Background technique [0002] At present, existing constant temperature and humidity units use compressors, heaters, and humidifiers to control cooling, heating, and humidification, respectively. However, since the cooling, heating and humidity loads of the unit are selected according to the maximum load of the working environment, when the required cooling load is small, the compressor has to be started and stopped frequently to match the environmental load, which affects the compressor's performance. The damage is great, so that the service life of the compressor is greatly reduced; and when the required heat load is small, the heating capacity of the heater is relatively large, which causes a serious waste of energy. Likewise, the same problem exists with the use of humidifiers. Contents of the in...

However, since the cooling, heating and humidity loads of the unit are selected according to the maximum load of the working environment, when the required cooling load is small, the compressor has to be started and stopped frequently to match the environmental load, which affects the compressor's performance. The damage is great, which greatly reduces the service life of the compressor; and when the required heat load is small, the heating capacity of the heater is relatively large, which causes a serious waste of energy

Similarly, the use of humidifiers will have the same problem
