The principle of liquid vaporization refrigeration is used 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 cooling and heating loads of the indoor environment. Generally, after the central air conditioner is produced, it is necessary to test its energy efficiency ratio so that it can be classified according to energy saving.
