The second step: the crystallization of salt impurities attached to the metal surface to form scale, or suspended in the water to become water slag

Summer high temperature and high humidity weather moisture condensation phenomenon is a common problem in the underground garage environment, especially in the rainy season in the south of China, the underground garage moisture condensation is particularly serious, not only for the use of the garage building structure performance and safety of the existence of a huge threat, but also long-term moisture will also affect the interior of the garage aesthetics, but also on the quality of the air inside the garage impact.

Multi-split air conditioner, also known as variable refrigerant flow multi-split air conditioning system, consists of an outdoor unit connected to a number of direct evaporative indoor units of different or the same type and capacity, constituting a set of single cooling/heating cycle air conditioning system, also referred to as VRV or VRF.

1, conventional air-conditioning design of the inlet and outlet water temperature difference of 5 ℃, large temperature difference air-conditioning system refers to the inlet and outlet water temperature difference greater than 5 ℃ air-conditioning system.

2, chiller chilled water supply and return water design temperature difference is usually 5 ℃, the chiller provides cold water supply and return water temperature difference and flow rate of chilled water;

3, the formula is as follows: Q = M * Cp * △ T;

4, where the specific heat Cp is assumed to be a constant, if the required cold Q unchanged, the temperature difference △ T increased, the flow rate M reduced. This reduces the water flow, increase the water temperature difference (greater than 5 ℃) of the air conditioning system called large temperature difference air conditioning system.

Gree air conditioning large 1.5 pi which model is the best to use, I think Gree YunTian, YunJin, YunShuOxygen, YunPei these four are very good models, but also Gree's best-selling series, the quality is very good, the configuration of the function is also complete, so it is recommended that you get!
