The constant temperature and constant humidity air conditioning unit has a lot of use in many industrial categories. This type of air conditioning unit is often a continuous operation, and the energy consumption is more natural. With the increasing situation of energy exhaustion, energy saving and emission reduction has become the main problem in China's birth enterprises, and the energy saving control of production enterprises is imperative. In many fine instrument manufacturers, the air conditioning unit that ensures indoor temperature and humidity is a component of high energy consumption.
Therefore, controlling and reducing the energy consumption of the constant temperature and constant humidity air conditioning system is the primary component of reducing the energy consumption of production. The energy saving thinking and design of constant temperature and constant humidity air conditioning system is the first problem that the vast engineering technicians need to face at present. The constant temperature and humidity center air conditioning system is separately in other air conditioning systems, which is the special requirement for the invariance of the temperature and humidity in the room. Some temperature wavering limits are required to be controlled within 1 degrees Celsius, that is, zero point five degrees centigrade floating up and down, and high requirements for humidity.
Temperature and humidity are not only controlled by external and indoor conditions, but also temperature and humidity will also affect each other. If it is at twenty degrees Celsius, when the temperature is shaken by one degree centigrade, the relative humidity will be swayed by about four percent. With the rapid development of machining technology, the smaller the temperature and humidity is, the higher the requirements of constant temperature and humidity air conditioning system, and the higher the energy consumption of air conditioning system. In order to reduce the energy consumption, necessary to carry out energy-saving design of constant temperature and humidity air conditioning system, and the constant temperature and humidity test chamber experiment, in addition, because of constant temperature and humidity air conditioning system using the traditional method of multi unit, rarely use the effective variable refrigerant volume air conditioning system. If the variable refrigerant flow of multi - body air conditioning is used, the cost of the cold and heat source of the constant temperature and constant humidity air conditioning can also be reduced, and the energy saving is completed.
As for the whole air system used, there is a scene of cold and heat offset in the air disposal, so that the energy consumption of the operation is greatly added. At present, the constant temperature and humidity air conditioning system and other air conditioning systems have a special local area, which is to design and build a high-precision constant temperature and humidity chamber, often using the whole air system.
