The air source heat pump cold and hot water unit can be used for both cooling and heating. Is there anything you should pay attention to in selecting the type of air source heat pump? I'll accompany you to have a look.
What should be paid attention to in the selection of air-source heat pumps?
As the central air conditioning cold storage in summer, the air source heat pump should take into account both the heating regulations in winter and the cooling regulations in summer. Especially in winter, the boiling water temperature during heating can reach 50 ℃, and the temperature difference of intelligent return water is 5 ℃; The cooling in summer is 7 ℃ cold water, and the temperature difference for intelligent return water is 7 ℃.
When the air source heat pump is used in four seasons and two seasons, there are two ways to select the volume: select the unit volume according to the heat load in winter, and then calibrate it according to the cooling load in summer, Or first select the unit volume according to the cooling load in summer, and then calibrate it according to the heat load in winter.
If, when selecting the unit volume according to the heat load in winter, the outdoor measured cooling capacity of air conditioning for coal to electric air source heat pump heating in summer is greater than the cooling load of engineering buildings, the general practice is to specify the air source heat pump unit, which should be selected according to the large specifications and models that meet the heating load in winter and the central air-conditioning load in summer.
In fact, the air source heat pump, cooling, and heating in different seasons will cause errors with the matching engineering building load. If the error is too large, it will be detrimental to the unit operation and actual effect.
