Pressure switch and pressure gauge
It is the most obvious advantage of air source heat pump heating compared with other heating methods. Moreover, compared with the hot water field with low profit, the profit space of the cold and warm water project is larger. Therefore, more and more air dealers are now investing in the cold and warm dual supply market. However, the requirement of design and installation of air source heat pump is higher.
1. Try not to use radiator at the end
Home mounted two-way supply system, the end of which is generally in the form of floor heating plus fan coil. Some users are limited by various conditions, but also installed with radiators or floor mounted fan disk. However, according to experience, if you can do the floor heating, try not to make a radiator, or the later operation cost will be higher than the floor heating.
Of course, if the floor of the user's home has been paved, then I suggest that the floor fan can be made, which is better than the radiator. Because the first radiator occupies too much area, the second thermal efficiency is also relatively low. If you have to use radiators, according to the ratio of wall mounted furnace and radiator, the number of radiators should be multiplied by 2, and copper aluminum composite radiator or special low-temperature radiator should be used.
2. Make the system as soft as possible
Many people may not pay much attention to the water quality when installing the floor heating and air conditioning dual supply system. Because of the different water quality in different places, the content of calcium and magnesium ions in some water is relatively low, which may not be a problem in the system. However, in some areas, the calcium and magnesium ions in the water are very high. When they are added to the system, they can be used for one year or two years at most, which may cause blockage of pipes, Y-type filters, water pumps, units, etc., seriously affecting the use.
