Business owners preparing to invest in a new refrigeration system must weigh all factors that impact their Total Cost of Ownership. Environmental impact and compliance — or lack of compliance — must loom large in those considerations. Supplier credibility is just as important — and Hillphoenix has over a decade of experience and over 1500 transcritical CO2 systems installed worldwide. Hillphoenix closes the deal with a commitment to provide guidance and training in the newest innovations and installation and maintenance best practices through the Hillphoenix Learning Center.
Here’s how it works.
The cooling cycle begins with liquid CO2 in the flash tank (receiver) (1) A network of pipes distributes the liquid to evaporators specially designed for optimum operation in CO2 transcritical systems. Electronic expansion valves (EEVs) are in place to control the flow of CO2 into those evaporators (2) Suction gas from the lowtemperature evaporators returns to the rack and is compressed by the subcritical compressors to the pressure of the medium-temperature evaporators (3) Suction gas from the medium-temperature evaporators returns to the rack and is combined with discharge gas from the low-temperature compressors and flash gas exiting the flash tank via the flash gas bypass valve (4) This mixture enters the transcritical compressors and is compressed to high pressure (5) From there it is sent to the gas cooler where it is cooled to near ambient temperature — in cooler weather, the CO2 in the gas cooler condenses similar to conventional systems (6) From the gas cooler, the CO2 enters the high-pressure control valve where it is expanded back to subcritical pressures (7) The CO2 then enters the flash tank where it is separated into liquid and gas — and the cycle begins again.
