Low ambient temperature screw air source heat pump

Low ambient temperature screw air source heat pump

Low ambient temperature screw air source heat pump is flexible for different applications of heating at very low ambient temperature -25 ~ -35℃ to produce 50℃ hot water, available hot water temperature range : 35- 50℃ heating function.

H.Stars Group has manufactured heat pump 28 years and can supply high competitive advantage low cost heat pump. The standard "low ambient temperature" air source heat pump adopts specialized compressors, which can be divided into two categories: scroll and screw type. It is also called air to water heat pump and It adopts modular control to give options of single control or multiple modules control. 

Low Ambient Heat Pump Compressor
1. Designed for cold areas, the cooling and heating dual function compressor has a minimum suction saturation temperature is -40℃ and a maximum suction saturation temperature is 15℃ .
2. Large heating capacity, suitable for central cooling and heating projects, reduce the initial investment and minimize the installation space.
3. With high efficiency oil separator to reduce the oil concentration of the system to increase the efficiency.
4. Double electronic expansion valve is adopted to control the unit body temperature to ensure the safety and the efficiency, low-temperature heating efficiency of is higher than the small compressor unit.
5. Screw heat pump no need external oil cooling device, system is simple and reliable.

Fin Type Heat Exchanger
1. Special design for low temperature , effectively extend the heating life cycle of the equipment.
2. Stainless steel frame design, good anti-corrosive performance,
strong and durable.
3. Special coated aluminum sheet, durable and difficult to frost.

Shell And Tube Condenser
1. Water through tube, easy to maintain and easy to apply for mechanically clean.
2. Adopt 1.1mm enhanced copper tube, self-developed core components to ensure the production process.
3. Qualified pressure vessel design and production.
Product Features And Functions
The HMI directly displays the fault content to cooperate with the simple operation interface to timely feedback various maintenance information.
The control system can be connected to the user's central control system (BMS) to monitor the chiller running situation freely.
Protection control on the external power supply system with Over-voltage, under-voltage, three-phase unbalance, and lack- phase protection.
And the chiller has built in more than 30 protection functions to provide comprehensive protection for the safe operation of the unit.
User connection points is reserved to provide cloud services.
