Air-conditioner and desiccant dehumidification of Principle
At present, as the people's standard of living is increasing day by day, and the high quality of the living environment needs Most are equipped with air conditioning dehumidification function, however, and the dehumidifier is the working principle of a distinction, According to the different environment, the selection of dehumidification mode is effectively regulated environment comfort the key.
Most of the human humidity of 60% to 70% in the air most comfortable environment, which is higher than the 70% humidity, Human comfort will drop, air conditioners and dehumidifiers.com.cn" target="_blank"> dehumidifiers adjustment humidity is so human reach a certain comfort, both work the same way also a different point, the following brief account of their work principles. 1. Principle desiccant air conditioner
In both air-conditioner model with dehumidification function :
A) cooling mode, it is an air-conditioner have model air conditioner is the most basic function. Air-conditioner cooling process is bound to be accompanied by dehumidification, moist air through the air conditioner evaporator after the temperature has dropped dramatically. humidity in the air over a saturation point, excess water vapor condensing in the form of precipitation, condensation on the evaporator fins, It is said, "Dewdrops," when cooling mode to achieve a certain balance, the air humidity has dropped to a certain level.
B) Independent dehumidification mode in this way by the industry as thermostats dehumidification, Its basic principle is to be through the evaporator cooling of the air again to the original heating temperature, and then sent indoors, This indoor humidity dropped in the case remained relatively constant.
Heating temperature from drafts also have two methods : One is the use of electric heating devices to heat through evaporation on the air (see figure 1). Indoor air-conditioning in these aircraft with electric devices, as the air through evaporation (surface hypothermia) precipitation condensing water, by electrothermal heating device that has been part of the cooling air, drafts and air conditioners out of the air inlet temperature consistent; Another is the use of condenser heat by heating the air dehumidification (see figure 2). Air-conditioning such a, b 2 switches, the independent dehumidification mode switch for each evaporator and the condenser, the same air through the evaporator a (low-temperature surface) precipitation condensing water, by the condenser b (surface heat) is an alternative approach which the electric components, the same air-conditioner to make out drafts and air inlet temperature of the basic agreement. This means only two heating heater and heating pieces of different ways, the latter purely physical way.
2. Desiccant dehumidification principle, the principle, simple is the use of the air entering the water dehumidifier condensate evaporator when frosting, and then accumulated drop out into Xiashuikou. reduce the space so as to achieve the purpose of humidity. Principle and its air-conditioner refrigerant dehumidification mode similar principle. Only dehumidifier compressor, condenser dedicated dehumidifier, with humidity controller to control the humidity and temperature controller is not controlling the temperature. |
