From environmental comfort air conditioning can be divided into: basic common air conditioning and constant temperature and humidity air conditioning, common air conditioning both household air conditioners and commercial air conditioning, all means only to adjust the air temperature, the humidity is just a by-product of the cooling or heating process, not to adjust the humidity, that is to say, a certain space, from 22 ℃ to 35 ℃ cooling, final temperature stability in 22 ℃, while in the process of refrigeration with desiccant, but the humidity is always the temperature fluctuates motionless, not artificial regulation, ordinary refrigeration with desiccant, the average relative humidity between 75% to 95%, from the comfort of consideration, although the relative humidity is very high, but the absolute humidity is low, so you will feel will often open air conditioning room very dry, nasal congestion, etc., which is commonly known as the air-condition disease, high relative humidity, absolute humidity is high, the relative humidity here refers to the relative humidity of air conditioning wind, also is 16 ℃, relative humidity, when the cold air indoors slowly rising inflation after the relative humidity will be lower than 45%, so the air is very dry, in addition to comfort requirements, production technology has higher requirement for temperature and humidity, constant humidity and constant humidity, these are all common air conditioning can't complete air conditioning.
Structure, common air conditioning and constant temperature and humidity air conditioning refrigeration system is a complete, they will be included to provide compression power of compressor, the cooling of the condenser, the throttling device, cooling/heating of the evaporator, commonly known as the four big air conditioning, constant temperature and humidity air conditioning is on a basic set of refrigeration system upgrade and optimization, constant temperature and humidity air-conditioning in addition to the above four parts, including the heating system and humidifying system, and control more advanced and accurate than common air conditioning, refrigeration and heating are balance, heating and humidification are balanced, constant temperature and humidity unit is a dynamic balancing system, but the dynamic balance system is based on balancing system based on humidity priority, so it is not hard to see, for temperature and humidity control, the difficulty and humidity control, a regular precision air conditioning, temperature can be plus or minus 0.1, technical implementation is not difficult, but the humidity do plus or minus 1%, but few enterprises can complete, such as Japan, the United States to air conditioning precision high, according to the their equipment may repeatedly debugging qualified reluctantly, domestic enterprises such as the west valley, refrigeration, etc., started with the technology as the enterprise, through years of experiment, to gain a foothold in the industry of high precision constant temperature and humidity. At the same time the west valley precision constant temperature and humidity air conditioning refrigeration production installation, constant temperature and humidity air-conditioning energy saving. Consultation telephone: 4000660810. Although, air conditioning has 100 years history of development history, but also for the future development of air conditioning is very big, subdivided market continues. The trend of the development of the industry, is also the trend of the development of the air conditioning industry.
