High Efficient Central Air Conditioner Heat Pump Intelligent Management
Central Air Conditioner Heat Pump Features
(1) The air source heat pump system is a combination of cold and heat sources. There is no need to set up a special freezer room or boiler room. The unit can be placed on the roof or the ground at will, without occupying the effective use area of he building. The construction and installation is very simple.
(2) The air source heat pump system has no cooling water system, no cooling water consumption, and no power consumption of the cooling water system. In addition, there have been many reports of Legionella infections caused by cooling water pollution. From the perspective of safety and hygiene, considering air source heat pumps also has obvious advantages.
(3) Air source heat pump system Because the boiler is not needed, the corresponding boiler fuel supply system, dust removal system and flue gas emission system are not needed, the system is safe and reliable, and has no pollution to the environment.
(4) Air source heat pump The cold (hot) water unit adopts modular design. It does not need to set up a standby unit. During the operation, the computer automatically controls and adjusts the running status of the unit to make the output power adapt to the working environment.
(5) The performance of air source heat pumps will vary with outdoor climate changes.
(6) In places where the outdoor air temperature in the north of China is low, an auxiliary heater is required due to insufficient heat supply in the winter of the heat pump.
