无标题文档 Mini Swimming Pool Heater Pumps LANDO Mini Swimming Pool Heat Pumps can be widely applied at family, school, hospital, hotel, factory and etc. The units can provide hot water for users all the day. Air source heat pump water heater It can produce hot water up to 60 degrees. * Flow switch inside for water flow protection.( EVI )* With circulation pump inside.* Running between 7 C to 43 C.* The running life will be ten years with low maintenance cost. * Safe and High Efficiency.* The connection between heat pump and water tank  is water piping. SELECTING A HEAT PUMP POOL HEATER Heat pump pool heaters cost more than gas pool heaters, but they typically have much lower annual operating costs because of their higher efficiencies. With proper maintenance, heat pump pool heaters typically last longer than gas pool heaters. Therefore, you'll save more money in the long run.  When selecting a heat pump pool heater, you should consider its: ●Size ●Efficiency ●Costs. DETERMINING HEAT PUMP SWIMMING POOL HEATER EFFICIENCY The energy efficiency of heat pump swimming pool heaters is measured by coefficient of performance (COP). The higher the COP number, the more efficient. However, there is no standard test for measuring the COP. Therefore, you really can't compare the COPs of different models unless you know that the manufacturers used the same test for each model. For example, the same heat pump will operate at a higher COP when the outside air temperature is higher.  Typically, manufacturers measure the COP by testing a heat pump pool heater with an outdoor temperature of 80ºF and pool temperature of 80ºF. COPs usually range from 3.0 to 7.0, which converts to an efficiency of 300%–700%. This means that for every unit of electricity it takes to runs the compressor, you get 3–7 units of heat out of the heat pump. !doctype House Swimming Pool Heat Pumps Specification : LD70-Xti-M LD140-Xti-M LD70-Xti-A LD140-Xti-A LD-03STi-H Air /Water   24℃/26℃ Output Power (KW) 4.50 7.80 4.50 7.80 15.11 Input Power(KW) 0.90 1.56 0.90 1.56 2.66 COP 5.00 5.00 5.00 5.00 5.66 Current 4.10 7.10 4.10 7.10 12.64 Air /Water 15℃  /26℃ Output Power (KW) 3.70 6.40 3.70 6.40 12.46 Input Power(KW) 0.86 1.49 0.86 1.49 2.68 COP 4.30 4.30 4.30 4.30 4.65 Current 3.90 6.80 3.90 6.80 12.40 Air /Water 7℃ /26℃ Output Power (KW) 3.20 5.50 3.20 5.50 10.45 Input Power(KW) 0.84 1.44 0.84 1.44 2.67 COP 3.80 3.80 3.80 3.80 3.92 Current 3.80 6.50 3.80 6.50 12.30 Electric Power 220~240V/1PH/ 50Hz 220~240V/1PH/ 50Hz 220~240V/1PH/ 50Hz Compressor HITACHI/ Rotary   HITACHI/ Rotary   Panasonic/    Scroll Heat Exchanger Titanium Tube in PVC Shell Titanium Tube in PVC Shell Titanium  Tube in PVC Shell Refrigerant R410A R410A R410A Defrost NO Included Included Remote NO / Mechanical Control 5m Signal wires /Intelligerant Control 5m Signal wires /Intelligerant Control Cabinet Galvanized  steel sheet coated Galvanized  steel sheet coated Galvanized  steel sheet coated Nozzles Size (mm) Exterior 50mm/        Interior 40mm Exterior 50mm/       Interior 40mm Exterior 50mm/  Interior 40mm Fan Power Input (w) 60 80 60 80 160 Fan Power Output(w) 18 25 18 28 90 Fan  (RPM) 870 870 870 870 850 Noice    dB(A) 46 47 46 47 55 Water Flow Rate(m3/h) 3.5 5 3.5 5 9 Product Dimension(mm) 750*325*470 930*360*550 750*325*470 930*360*550 1100×410×880mm Packing  Dimension(mm) 855*330*530 1060*380*600 855*330*530 1060*380*600 1120×410×995mm Net/ Gross  Weight(kgs) 37/40 49/54 37/40 50/55 90/95
