Transcritical CO2 (R744) Supermarket Refrigeration in Australia. By the Australian Green Cooling Council. Abstract. Conventional supermarket refrigeration

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。

A typical CO2 transcritical booster system is di-vided in to three pressure sections, High pressure 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.

Manifold and hoses designed specifically for transcritical C02 (R-744) applications. The YELLOW JACKET ® TITAN ® Test and Charging Manifold for transcritical CO2 systems is constructed with a forged aluminum alloy body making it lightweight for easy handling and durability. No sight glass for added safety.

Transcritical R744 (CO2) heat pumps . Rapport 2414173 - October 2007

CO2-Transcritical; Hussmann Waterloop; CO 2 / Transcritical Some Background . CO 2 (R744) was one of the first refrigerants used back in the mid 1800s through until the 1920-1930s. It was then phased out in favour of the newly developed CFC refrigerants. Discover the Inverter transcritical iCOOL CO2 Hvac Condensing Unit from Area Cooling.
