Why does the hotel central air conditioning have uniform cold and hot air?

The reason why the central air conditioning of the hotel is unified in cold and hot air is because the system composition is different. According to relevant information, the central air conditioning system of the hotel is composed of one or more cold and heat source systems and multiple air conditioning systems. This system is different from the traditional refrigerant air conditioner, and can centrally treat the air to meet the comfort requirements. The hotel central air conditioning adopts the principle of liquid gasification refrigeration 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 load and heat load of the indoor environment.
