What's the difference between central air conditioning and household air conditioning?

1. Central air conditioning: It consists of one or more cold and heat source systems and multiple air conditioning systems. This system is different from the traditional refrigerant air conditioner, such as VRV, which centrally processes air to meet the comfort requirements.

2. Household air conditioner: it is an air conditioner installed in residents' own homes.

Second, the role is different.

1, central air conditioning: the principle of liquid gasification refrigeration is adopted to provide the required cooling capacity for the air conditioning system to 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.

2. Household air conditioning: adjust indoor temperature and humidity to purify the air. It is an ideal advanced household appliance for modern families.

Third, the principle is different.

1. Central air conditioning: refrigeration is realized by using the heat absorption when liquid is vaporized and the heat release when it is condensed. Liquid evaporates to form steam. When the liquid (refrigerant) is in a closed container, there is no other gas except the liquid and the vapor generated by the liquid itself.

2. Household air conditioner: The compressor sucks the working medium vapor with lower pressure from the evaporator, and sends it to the condenser after the pressure rises, where it condenses into a liquid with higher pressure, which becomes a liquid with lower pressure after being throttled by the throttle valve, and then sends it to the evaporator to absorb heat and evaporate into steam with lower pressure.
