Supply air heat pump - air heat pump design - air heat pump professional manufacturers in Guangdong

In the swimming pool heat pump applications, has the following characteristics: 1 unit larger size standard large pool (50m * 25m) of water, up to 1500T time, although the temperature rise is not, but the total heat demand is still very large, in order to 1500m swimming pool for example. Increased by 1 ℃, is 15 * 10kcal, if using a 10 air-source heat pump heating it, assuming the ambient temperature is 20 ℃, COP unit 5, an input power of 8KW, the hourly production heat is Q = 5 * 8 * 860 = 34 400kcal, even without considering the heat loss of pool water, to complete the task to increase temperature 1 ℃ also need 43.6H. So generally require a larger stand-alone power unit. 2 low water temperature, water temperature high efficiency unit requires general pool of 26-29 ℃, which can easily reach the air source heat pump, since the low temperature of the condenser, the condenser can be designed smaller in the pool conditions, the heat pump high efficiency of the unit, at an ambient temperature of 20 ℃, generally can reach more than 550%. 3 high quality requirements according to the national standards, in order to ensure sanitary conditions, swimming pool water quality demanding, regularly finishing quality, and these added components are highly corrosive to metal, therefore, dedicated swimming pool units, condenser air source pool Dongguan tee environmental protection unit are excellent with anti-corrosion titanium and copper-nickel, copper-aluminum alloy material. More at ease when in use. 4 condenser water flow due to the different pools and the preparation of domestic hot water requirements of heating requirements are also different, in general the heat pump water heater products in order to improve the efficiency of the system, generally reasonable arrangements for the pump flow rate, according to the design specifications condenser temperature difference between imports and exports of 5 ℃, but in the pool, this temperature difference has been enough to make swimmers feel unwell, it is necessary to reduce the temperature difference, the method that is to increase the circulating water flow, and the heat pipe heat exchanger common , flow resistance, it is not suitable for these conditions, Dongguan tee environmental protection unit uses air source pool with good circulation tube - tube heat exchanger. So that the pool water to maintain a comfortable temperature, more comfortable use.
