Air-cooled scroll chiller (heat pump) is a central air conditioning unit that uses air as cooling or heating source, and water as secondary refrigerant. It can be combined with multiple air side equipment, like fan coil and AHU, to form a centralized air conditioning system.

Product Parameter:

Product Feature:

Efficient flexible scroll compressor

The unit uses the well-known hermetic efficient scroll compressor and the optimized scroll and sealing ring so that the refrigerant compressor features axial and radial flexibility. This not only effectively reduces refrigerant leakage, but also raises the volumetric efficiency of the compressor. Moreover, each compressor is equipped with a unidirectional discharge valve to avoid backflow of the refrigerant and ensure that the compressor can run stably in the full operating condition.

FAQ:

Q:What to pay attention to when installing air cooled scroll chiller?

A:1. For the unit with less than 80 tons of cooling capacity, recommend DN100 as the main water outlet pipe and installing water outlet/ inlet pipes on the same side.

2. For the unit with cooling capacity between 80 tons and 160 tons, recommend DN125 as the main water outlet pipe and installing water outlet/inlet pipes on the same side.

3. For the unit with cooling capacity between 160 tons and 240 tons, recommend DN150 as the main water outlet pipe and installing water outlet/inlet pipes on the same side.

4. For the unit with cooling capacity between 240 tons and 500 tons, recommend DN200 as the main water outlet pipe and installing water outlet/inlet pipes on the same side.

5. The water outlet and inlet connection pipes of the unit: For the pipe connection dimensions of the unit, see the specifications table. The main water pipe is installed by the engineering personnel according to the actual situations.
