Co2 Evaporator System

Evaporators can be designed for pumped dx or brine operation to be compatible with all system types.

Co2 evaporator system.

System condensing temperatures for part or all of the year depending on the climate. Nh3 co2 cascade systems are safer for workers in refrigerated facilities. Haffmans co2 evaporation heat recovery system. Using co2 on the low side of a cascade system is safer for people and eliminates the risk of damage to products in the event of a leak.

The required evaporation heat is provided by available hot cooling medium which during the evaporation process is cooled down. One is found on the low side co2 portion of the system and a second on the high side which controls the compressors for the secondary refrigerant. The blowers force the ambient air to the surface of finned tubes vaporizing and heating the co2. There are two differences from the traditional system.

To efficiently operate a system such as this key elements of consideration were use of electronic expansion valves for each evaporator required in a co2 system distributed controls allowing plant operators visual indication of system operation features refrigeration defrost alarm cleaning etc and distributed smart controls which. The tubing and pipe used in the evaporator is the main determinant of its pressure bearing capability. How tpi system works. Transcritical or subcritical cascade or single stage.

A refrigeration system which includes a compressor condenser evaporator coil and some variety of expansion device. Co2 r 744 systems operate at higher pressures than other refrigerant systems. One is the gas cooler that takes the place of the condenser and the other is the expansion device. The evaporation system consists of one ambient air heated evaporator double circuit and a pressure reducing station.

Find a local sales office select category refrigeration evaporators dry coolers condensers heating cooling coils heat pipes for heat recovery. Evaporators for co2 refrigeration. There is no phase change figure 3. Using co2 on the low side of a.

R 744 co 2 phase diagram the critical point is the condition at which the liquid and. Co 2 systems that are designed to operate at pressures above the critical pressure of 1055 psig. Above the critical point the refrigerant is a supercritical fluid. The haffmans co 2 evaporation heat recovery system liquivap is a heat exchanger designed to automatically evaporate liquid co 2 running from the co 2 storage tank s.
