Heat Pump Heating Cooling Air Conditioning Outdoor Machine Split system Main advantages Using air source heat pum(ASHP) for air conditioning is four times efficient than Commen air conditoner outdoor unit. The operating cost is only 1/4 of the electric boiler and 1/3~1/2 of the gas-fired boiler, which not only saves a lot of electric energy, but also saves operating costs. Other advantages: Safety: There is no electric heating equipment in the air source hot water tank. Only the air energy source is continuously transmitted to the hot water tank during operation, there is absolutely no leakage, electric shock, explosion, poisoning, etc. Environmental protection: no waste heat, waste water, exhaust gas and other harmful substances will be discharged indoors or outdoors. Comfort: The water system has high stability and can maintain a constant indoor temperature. In addition, the heating and cooling methods are closer to the human body's temperature, which makes the refrigeration and heating more comfortable and does not cause hot and cold heat to the user. a feeling of. YUSHEN Products It could work in extreme environment /Suitable for environmental temperature:-25℃ to +45 ℃ /-13℉ to 113 ℉ Quality Components such as Copeland compressor, Danfoss valves 100% finished products testing Having only one unit which could both heat and cool to maintain means lower repair costs and less work in general Testing ceter
