The air-cooled chiller is based on modular technology, uses air as the cold (heat) medium, and is an integrated central airconditioning equipment with both cold (heat) sources. The air-cooled modular units on the market are divided into single refrigeration type and heat pump type. On the market, air-cooled modular units generally refer to heat pump-type air-cooled modular units, also known as air-cooled heat pump units.
The unit has the advantages of high efficiency, low noise, reasonable structure, easy operation, safe operation, convenientl installation and maintenance, etc. It is widely used in hotels, shopping malls, office buildings, exhibition halls, airports, stadiums and other public places. And it can meet the different use requirements of the air-conditioning system in the industries of electronics, pharmacy, biology, textile, chemical industry, metallurgy, electric power, machinery and so on.
The unit adopts high-efficiency heat exchanger, advanced and special outdoor structure design and system matching. The unit is small in size, light in weight and occupies less land. The unit can be installed directly on the roof or other outdoor places, without the need for another machine room, which can save space.
The unit is equipped with protection devices such as temperature protection switch, overload relay, high and low voltage safety switch, dry filter, antifreeze switch and delay start to ensure the safety and reliability of the main engine. All refrigeration accessories and valves adopt international famous brand products to comprehensively improve the operation reliability of the unit.
The design of the modular structure enables the unit to be produced and transported in standard modular units. Combined into a complete unit at the installation site, the standard modular unit is light in weight and small in size, which makes the transportation, installation, commissioning and maintenance of the unit more convenient, and saves lifting, installation and operation costs.Modular air-cooled chilled water heat pump unit, each refrigeration system is independent of each other and serves as backup for each other. The abnormality of any refrigeration circuit will not affect the normal operation of other refrigeration circuits. When a circuit fails, the computer will issue an instruction to replace the operation of the faulty circuit with other standby circuits. In this way, the cooling and heating capacity of the unit remains relatively stable.
Exquisite and beautiful appearance
The air-side heat exchanger is made of high-efficiency internal threaded copper tubes and corrugated reinforced aluminum fins made of hydrophilic film materials through mechanical expansion. It has the characteristics of high efficiency and is not easy to ash, especially in winter. The “V” coil design is adopted, the space utilization rate is high, the overall size of the unit is small, and the wind speed on the surface of the coil is more uniform, which effectively improves the airflow organization.l The relevant parts of the unit and the system piping are arranged rationally, equipped with “v” type coil and integral structure design, which makes the appearance of the unit clear and smooth.The casing of the unit is treated with powder electrostatic spraying, and the color is uniform and beautiful. Users can choose the color they like, or choose stainless steel plate as the casing, which is anti-corrosion and anti-rust. To adapt to the harsh outdoor weather conditions, to ensure that the unit has a good appearance quality within the service life cycle.
Ultra low noise
High-efficiency hermetic scroll compressor is adopted, with stable operation and low noise and vibration. The well-known brand axial flow fan is adopted, which is compact in structure and conforms to the principle of aerodynamics; the sickleshaped impeller enables the fan to operate efficiently with low noise, and maintains good aerodynamic performance even in short wind conditions.
Advanced control, stable quality and reliable performanceThe unit adopts well-known brand compressors, fans, refrigeration system accessories, computers and electronic control components, with stable quality, accurate control and reliable performance. It has strong adaptability to various harsh working conditions, simple maintenance and high operating efficiency. Adopt advanced microcomputer control technology, full Chinese man-machine display interface, friendly operation interface, users can know the operation status of the unit at any time.With high degree of automation and complete functions, it can realize unit start-stop program management, timing control, centralized monitoring and remote monitoring of units (optional).The microcomputer controller has intelligent defrosting, the defrosting is accurate and effective, and the heat loss is avoided. At the same time, it has multiple automatic control functions such as fault diagnosis, energy management, antifreeze monitoring, and operation mode to ensure efficient operation of the unit. The unit is equipped with multiple safety protection devices such as high and low pressure, antifreeze, oil temperature protection, overload protection, phase loss and reverse, etc., to ensure the safe operation of the unit.
Maintenance management, convenient and fast
The installation of the unit is flexible, and it can be controlled on site or remotely; the unit adopts an open structure, and its compressor, refrigeration accessories and electric control system are all placed in the lower part of the unit, which has a large maintenance space and is convenient for maintenance.
