Air Source Heat Pump Commercial Screw Chiller

Air source heat pump air to multiple functions with hot water, air conditioning, heating, so it is a typical energy saving hot water refrigeration equipment, energy efficiency, energy efficiency ratio as high as 8, making full use of energy. Air source unit with a small amount of electricity in the air heat transport to the water heating water, consumption of energy is electric water heater 1/5 gas water heater; 1/6; fuel heater 1/4; ordinary solar 2/3; use of low power and can achieve more energy saving effect. It is not affected by the environment is a hot water supply system of all weather, regardless of cloudy and rainy days, the spring and autumn and winter, day and night, as long as there is hot air, can be heat energy of low temperature -10 to 30 DEG C, through the air heat pump air to provide temperature up to 60 degrees Celsius hot water.

Characteristics
01.The compressor. The Air cooled screw chiller is equipped with semi-hermetic screw compressor, compared with the piston compressor, semi-hermetic screw compressor has two advantages: Less parts ( About 1/3 of the piston compressor ), simple structure, less wearing parts, high reliability and long life. Compressor suction and exhaust uniform, exhaust temperature is low, vibration is small, not sensitive to wet compression, anti-liquid strike ability.
02.Tube-fin air-cooled condenser. The tube-fin air-cooled condenser adopts the inverted "V" type layout, on the one hand, it improves the space utilization ratio, increases the heat exchange area, on the other hand, it improves the airflow and heat transfer efficiency, so that improve the unit's cooling and heating capacity.

03.Throttling equipment. For expansion valve, we select the most advanced products, with a compact overall design, rugged stainless steel diaphragm, and in a wide range of operating conditions to provide stable and accurate control.
04.Tube-shell evaporator. Using shell and tube structure, the outside is proceeded with fire-retardant,waterproof insulation materials, water side of the working pressure is 1.0MPa. Evaporator with PVC plastic water board, corrosion resistance. Chilled water along the diaphragm up and down circuitous flow, in order to increase the spoiler effect to improve the evaporator heat transfer capacity. Using the latest DAC corrugated spiral high efficiency heat transfer tubes, strengthen the fluorine side heat transfer capacity, improve the heat transfer coefficient to ensure that the unit good refrigeration and heating performance.

05.Electronic control. Air conditioner unit uses a microcomputer as the core of the control system, the control system control precision, anti-interference ability to ensure that the unit safe, reliable and economical operation. Energy regulation automatic control can make the unit always in the best economic mode point efficient operation. Protection function complete unit with overload, short circuit protection, frost protection, high and low voltage protection, overheating protection and other functions.
