What does central air conditioning mean?

Central air conditioning is an air conditioning system composed of one or more cold and heat source systems and multiple air conditioning systems. The system is different from the traditional refrigerant air conditioner, and adopts centralized air treatment to meet the comfort requirements. The principle of liquid gasification refrigeration is adopted to provide the required cooling capacity for the air conditioning system and offset the heat load of the indoor environment; The heating system provides the required heat for the air conditioning system to offset the cold and heat load of the indoor environment.

Refrigeration system is an important part of central air-conditioning system, and its type, operation mode and structural form directly affect the economy, efficiency and rationality of central air-conditioning system.

Extended data

Features of central air conditioning:

(1) Efficient and energy-saving: adopt a modular host, and automatically adjust the cooling capacity according to the setting. The reasonable way is to install air conditioners in the daytime living quarters and the nighttime living quarters respectively, and control the rooms in different areas, and operate independently indoors to adjust the air in each area respectively.

(2) Good comfort of household central air conditioning: the design of central air conditioning is adopted, with large air supply volume, small air supply temperature difference and uniform room temperature. Different from split air conditioning, which has only one air supply mode, home central air conditioning can realize multiple air supply modes, and make different plans according to the specific situation of room type.

(3) Beautiful appearance: A comprehensive solution from design to installation can be implemented according to users' needs and preferences. The system adopts concealed installation mode, which can cooperate with high-grade interior decoration. At the same time, due to the reasonable placement of outdoor units, the overall appearance of the building will not be destroyed.

(4) Four seasons operation: the refrigeration unit runs in summer to realize cold regulation; Heating in winter can be realized by using cold machine combined with heat source.
