Air conditioning classification: comfort air conditioning - temperature as the main object of control to meet the requirements of human comfort; precision air conditioning - temperature and relative humidity as the main object of control to meet the requirements of industrial production (constant temperature and humidity); clean (purification) air conditioning - the number of air particles as the main object of control to meet the requirements of industrial production (cleanliness).

Refrigerant is an indispensable part of the air conditioning system, but its usage is often difficult to control precisely. When the refrigerant is insufficient, it may lead to a decline in the performance of the air-conditioning system, a deterioration in the cooling effect, or even malfunction. Therefore, it is particularly important to accurately determine the refrigerant charge.

The temperature of the air outlet surface and the indoor ambient temperature (or the temperature around the air outlet) is too large a difference, the surface temperature of the air outlet is low, coupled with the high humidity of the indoor air, resulting in indoor machine air outlet condensation, air conditioning outlet condensation is a normal phenomenon.
Although condensation dripping is a normal phenomenon, this may lead to moisture and mold on the wall, or even wall paint peeling, both affecting the aesthetics of the home and the use of air conditioning. So how to deal with it?

In recent years, with the social and economic development, on the one hand, people have higher and higher requirements for living environment, and the five permanent residences with the characteristics of constant temperature, constant humidity, constant oxygen, constant cleanliness and constant staticness can satisfy people's demands for a good living environment; on the other hand, how to make the five permanent residences air conditioning system energy-saving and emission reduction, and how to reduce the carbon emission of the whole life cycle has become a big challenge. Wuhang residence adopts capillary radiation + fresh air dehumidification air conditioning system, capillary cooling and heating source usually adopts ground source heat pump, the system has high efficiency and low carbon and environmental protection, and the fresh air treatment needs high grade cold source, so how to improve the efficiency of the fresh air treatment, reduce the energy consumption of the fresh air treatment, and make the system economic and reasonable, energy-saving and high efficiency, low carbon and environmental protection become the key of the air conditioning system.
