Air source heat pumps have the following characteristics
(1) The air source heat pump system combines hot and cold sources into one, and does not require a special refrigeration room or boiler room. The unit can be placed on the roof or the ground arbitrarily, without occupying the effective use area of the building, and 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 cooling water system power consumption. In addition, many cases of Legionella infection caused by cooling water contamination have been reported. From a safety and health perspective, air source heat pumps also have obvious advantages.
(3) Since the air source heat pump system does not require a boiler, corresponding boiler fuel supply system, dust removal system and flue gas emission system, the system is safe, reliable and has no pollution to the environment.
(4) The air source heat pump cold (hot) water unit adopts a modular design, so there is no need to set up a backup unit. During operation, the computer automatically controls and adjusts the operating status of the unit to adapt the output power to the working environment.
(5) The performance of air source heat pumps will change with changes in outdoor climate.
(6) In areas with low outdoor air temperatures in northern my country, auxiliary heaters are required due to insufficient heat supply by heat pumps in winter.
