Air Cooled Chiller Refrigerant
Product introduction
Air-cooled screw type cold (hot) water unit is based on air as a cold (hot) source, water as a refrigerant, it can be cooling and heating, and can run all year round, with environmental protection, energy saving, comfortable, stable characteristics.
GRAD air-cooled screw cold (hot) water unit embodies the essence of design, manufacture and application, the unit has low temperature, strong heat, multiple protection Freezing, intelligent defrosting, intelligent control and other core technologies, high operational reliability, wide range of operation, product diversity, widely used in hotels, shopping malls, office buildings,exhibition halls, airports, stadiums and other public places, and can meet the electronic,pharmaceutical, biological, textile,Chemical industry, metallurgy, electric power, machinery and other industries.
Features of GRAD Air Cooled Screw Chiller
1、A single unit can replace 9 units of 20P scroll ultra-low temperature air source heat pumps
2、There is no need to build a machine room. Under the same heating area, the floor space occupied is 50% less than that of the scroll unit
3、It can produce hot water at a maximum temperature of 85℃, and at an ambient temperature of -35℃, it can produce hot water at 60℃
4、 High-efficiency and low-noise fan, with noise reduction of 4-6dB under the same working conditions
Advantages
1.It can operate stably in an ultra-low temperature environment of -35℃
2. Precise frost measurement, rapid defrosting, reduced defrosting frequency, and shortened defrosting time
3. Mobile APP operation, fault warning, and online diagnosis
4. It operates efficiently within an ultra-wide ambient temperature range of -35℃ to 43℃
5. COPh > 2.6 exceeds the national standard energy efficiency limit value, and IPLV(H) exceeds the national standard first-level energy efficiency
Working Principle
When the air-cooled water chiller is working, the refrigerant absorbs the heat from the cooled object in the evaporator and vaporizes. The compressor continuously draws the gas generated in the evaporator and compresses it into high-temperature and high-pressure vapor. The refrigerant vapor is then sent to the condenser to exchange heat with the air. After releasing heat, it condenses into liquid. The liquid refrigerant is decompressed after passing through the expansion valve. Then it enters the evaporator to absorb the heat of the cooled object and vaporizes again. This heat exchange process is repeated until the industrial water is cooled to the required temperature.
