Comprehensive understanding of multifunction air source heat pump
What is "dual supply"? Air source heat pump dual supply system is composed of four parts: outdoor host (air source heat pump), terminal equipment (indoor heat exchange and refrigeration system), transmission and distribution system, and control system. It can meet the two functional requirements of heating and cooling. It is the best choice for comfortable home in cold winter and hot summer areas.
Before the selection of heat pump host, it is better to know the local minimum temperature, average minimum temperature in January, water supply temperature and precipitation in advance; project building standards, new and old building envelope and door and window standards, to ensure the thermal insulation of doors and windows.
Transmission and distribution system
The transmission and distribution system includes energy storage buffer water tank, expansion water tank, water pump, pipeline valve, diversity water collector and water balancer.
Buffer water tank plays an important role in heat pump system, including enhancing stability, storage, buffer, automatic exhaust, protection, cleaning and other functions. The buffer water tank can increase the water capacity of the small system, store the cold and heat, make the temperature change of the system more stable, avoid the frequent start and stop of the unit when the main engine is running at low load, and effectively extend the service life of the main engine.
There are many types of common pumps, such as shield pump and centrifugal pump. Compared with the centrifugal pump with separate structure, the performance of shield pump is more stable and there is basically no leakage. In addition, the noise of the shield pump is basically lower than 45dB, which effectively reduces the noise during operation.
The water separator is composed of the main water distributor and the main water collector. The main water distributor is connected to the water supply pipe of the pipe network system. Its main function is to distribute the hot water from the pipe network system to the indoor rooms requiring floor heating through the floor heating pipe buried under the floor. When the hot water flows in the floor heating pipe, it transfers the heat to the floor, and then radiates to the indoor through the floor.
Terminal system
The end system includes fan coil, low temperature radiator, floor heating and capillary network.
Control system
The control system includes power supply, control line, control switch, etc., and the control panel is in the form of wired control, wireless, Internet of things intelligent control.
Personalized comfortable experience has gradually become the pursuit of many families. Air source heat pump with two-way supply and accurate temperature control, small indoor temperature fluctuation, quieter operation, and obvious economic advantages of energy efficiency and energy saving will become the mainstream choice in the market.
