Heat pumps shall be reversible air cooled Scroll type, with environment friendly refrigerant R-410a. Heat pump Shall have minimum 2 Compressors with independent circuits. The overall support frame and bottom plate of the unit Shall be made of galvanized steel sheet whose outer surface has to be painted, with high strength and strong anti-corrosion ability. The unit shall be equipped with compressor and refrigeration components as standard protective panels to protect the unit and effectively block noise transmission. It shall have silent operation and the sound level should not exceed 70 dB at 1 meter from the unit. The compressor motor should adopt suction cooling and there should be no directly contact with lubricating oil. Evaporator used must be high quality shell and tube/platetype heat exchanger. The close-cell thermal insulation material should be attached on the exchanger to prevent condensation on the external surface. The electric heater inside the exchanger shall be provided to avoid freezing in extreme environment. Unit must be capable to manage defrost cycles as per the prevailing environmental conditions.The air-side heat exchanger shall be finned tube type with U/H-shaped design to increase the effective area of heat exchange and have a high heat transfer effect. Copper tubes must be internally threaded, which also increases heat exchange area and refrigerant disturbance to improve heat transfer. Refrigerant cycle must have Electronic Expansion valve, to precisely control the gas flow to optimize the evaporator's performance. EEV must adjust the system based on the superheat degree of suction gas for reliable running."Heat Pump mjust be provided with Intelligent microprocessor with human-machine interface screen able to manage unit efficiently, to network and communicate well, protection - when under alarm and alarm management functions. Multi-language menu, shortcut key, graphic unit status. Average compressor running time to extend unit working life."
