◆ Huihui Refrigeration's screw-type air-cooled heat pump unit components are all treated with electrostatic phosphating spray by imported automatic spraying equipment, offering strong corrosion resistance and adaptability to harsh outdoor climates. This ensures the unit maintains excellent surface quality throughout its lifespan. The meticulously designed frame structure is simple yet elegant, with a dignified and generous appearance.

◆ Controller status display, parameter modification, and fault inquiry are all prompted by Chinese menus, making operation extremely simple.

The air-cooled screw chiller-heating water unit employs low-speed fans, and the compressor is enclosed by a noise-insulating cover lined with sound-absorbing cotton to reduce noise. It utilizes high-performance, low-noise axial fans designed according to aerodynamic principles, offering high efficiency and maintaining excellent aerodynamic performance even under short-airflow conditions.

◆ The screw-type air-cooled heat pump unit's capacity can be PLC-intelligently adjusted according to load conditions, matching operating capacity with actual load to enhance compressor efficiency and reduce power consumption. Utilizes an auto-correcting intelligent defrosting mode for accurate and effective defrosting, preventing heat loss.

◆ The screw-type air-cooled heat pump units utilize high-end European and American refrigerant system components from brands like ECO and Emerson, ensuring stable quality. The electrical control components and elements are sourced from brands such as Siemens and Schneider from Germany, guaranteeing reliable performance.

◆ Employed high-efficiency internal thread copper tubes and aluminum fin baffles, tightly sealed through mechanical expansion for optimal thermal transfer efficiency. The overall thermal transfer coefficient is improved by 67% compared to conventional coil tubes.

◆ Aluminum sheets are all treated with hydrophilic and anticorrosive properties, effectively reducing the thickness of the condensate film during heating operation, lowering the thermal resistance of the film, and enhancing the heat transfer efficiency of the coils.

◆ The screw-type air-cooled heat pump unit features unique tube arrangement, taking into account the changes in refrigerant state, flow rate, and pressure drop under cooling and heating conditions. The condenser coils in both cooling and heating modes offer high thermal transfer performance, ensuring sufficient subcooling (cooling) and superheating (heating) of the coils.

The screw-type air-cooled heat pump unit features a tube-and-shell structure, insulated with the latest flame-retardant, waterproof, and heat-insulating materials. The water side is capable of withstanding pressures up to 16 l,~gf/cm².

◆ The evaporator is equipped with a water-dividing plate, allowing the refrigerant water to flow around it in a zigzag manner to enhance turbulence effects. The evaporator inlet is specially designed to distribute the refrigerant more evenly throughout the copper tubes, thereby improving the overall thermal transfer efficiency of the heat exchanger.

     ◆ Utilizing the latest internal threaded high-efficiency heat exchange tubes, offering a thermal transfer coefficient 1-3 times that of common high-efficiency tubes. These tubes provide high heat transfer efficiency for both internal evaporation and condensation, ensuring excellent cooling and heating performance of the unit.

◆The Yin-Yang rotor is precision ground on a high-precision rotor grinder, featuring high volumetric efficiency, low noise, minimal vibration, and stable and reliable operation.

◆ Featuring a renowned brand fluorine-resistant motor, offering high efficiency and reliability. The motor is cooled by a low-temperature refrigerant, ensuring excellent heat dissipation and no possibility of leakage.

◆ Optional with free cooler, no need to turn on the compressor in winter. It can provide chilled water using the low outdoor air temperature, saving electricity up to 90%, and highly energy-efficient.

The air-cooled screw heat pump unit integrates multiple functions into one, simplifies equipment, simplifies construction work, does not require a dedicated machine room, occupies less floor area, and has a low engineering investment.

◆ The unit utilizes electrical and air energy, producing no waste gases or sludge that pollute the environment, thus providing users with a superior living environment. It recycles the waste heat from air conditioning condensers, reducing environmental thermal pollution.

The microcomputer controller of the screw-type air-cooled heat pump unit can automatically sense the load size of the air conditioning and hot water system, and adjust the corresponding compressor capacity output according to the fuzzy control theory, achieving a balance between the unit capacity and the air conditioning and hot water loads, thereby minimizing operating costs.
