Back in. 1994 the company was already busy with the first transcritical. CO2 compressor models for bus air conditioning. Today Bock offers two system versions ( 

R744 systems work transcritical when the gas cooler exit temperature is above 31 °C (88 °F). HFC systems always work subcritical because the condensing 2 (R744) has the significant advantages of having the lowest GWP, a very low refrigerant cost and excellent heat transfer. Transcritical CO2 only systems reject heat via a gas cooler, whereas cascade systems reject heat to another refrigeration circuit. Challenges that need to be overcome in applying CO 2 systems include system with liquid R744 for example. Solid R744 is also known as dry ice. The critical point occurs at 31°C, which is below typical system condensing temperatures for part or all of the year, depending on the climate.

The evaporator pressure is at kept at around 3.5 MPa and the gas cooler pressure is nominally around 10 MPa, which is above the CO2 (R744) critical pressure of 7.4 MPa. Hence, this is a transcritical refrigeration cycle. The gas cooler pressure changes in response to changing environment temperature. R744 systems work subcritical when the condensing temperature is below 31 °C (88 °F). R744 systems work transcritical when the gas cooler exit temperature is above 31 °C (88 °F).

The recent launch of CO2Y, Green & Cool's compact condensing unit, has been warmly Switching to natural refrigerants such as CO2 (R744) and hydrocarbons (R290 and R600a) Europe's first ice arena with transcritical CO2 refrigeration.

The COP of the system is evaluated including the use of heat reclaimed from the R744 system within the store. The total CO2 emission reduction of the supermarket by implementing this innovative refrigeration system is 冷媒は二酸化炭素 (co2) で、この用途では r744 とも呼ばれます。 コンプレッサーは、サイクルを通じて co2 の流れを駆動し、臨界圧よりも上に圧力を高めます。ガス冷却器は高圧の co2 から環境へ熱を放出します。 Manifold and hoses designed specifically for transcritical C02 (R-744) applications.
