Fluorine Pump Principles
Working principles of fluorine pump:
●
The fluorine pump is efficient and energy-saving. When the ambient
temperature is lower than –8°C (switches back to the compressor system
when the outdoor temperature is higher than –5°C), the cooling system
automatically switches to the fluorine pump for circulation through valve
control. The compressor is stopped, and a low-power refrigerant pump is used
for forced convection circulation of refrigerant. In this way, the indoor
evaporator provides cooling and the outdoor condenser dissipates heat
continuously. This mode ensures the cooling capacity equal to that of the
compressor, shortens the compressor runtime, and saves energy.
●
The fluorine pump mode also provides 12.5 kW cooling capacity when the
outdoor temperature (lower than –5°C outdoor) is low. The total power of the
equipment is 2.6 kW when the compressor is running, and it is about 1.2 kW
when the fluorine pump is running. The cooling capacity in 1.2 kW fluorine
pump mode is basically equal to that in 2.6 kW compressor mode.
