Specifications

1. The unit has 4 basic modules, which can be freely combined according to the required capacity. The cooling capacity range is 51-1300kW.

2. Patented split type dry evaporator (patent No.: ZL03227972.8) has high heat exchange rate and reliable return oil.

3. All module controllers are connected by common RS485 communication bus and each controller can work alone or in combination with multiple controllers.

4. Under partial load, the unit can adjust the output of the energy in a step-by-step manner of modular unit, so that it best matches with the load and saves significant energy.

5. The "increasing enthalpy by replenish gas" high-efficiency scroll compressor is adopted, so as to realize quasi-two-stage compression of the system; the refrigerant circulation amount is increased, to avoid the problem of reducing heating capacity under the low-temperature conditions; and the exhaust gas temperature is lowered to meet the heating requirements under the ambient temperature of -25 ℃.

6. The patented ice suppression technology of fin heat exchanger eliminates the "ice climbing" phenomenon of the fin heat exchanger, improves the operating efficiency, and ensures thorough defrosting.
