Anläggningsteknik CO2 R744 Svensk Byggtjänst

View MATLAB Command. This example models a vapor-compression refrigeration cycle in which the high pressure portion of the cycle operates in the supercritical fluid region. The refrigerant is carbon dioxide (CO2), also called R744 in this application. 2021-01-25 CO2 (R744) By utilising a natural refrigerant within a cooling system, the specifier is able provide a number of benefits that can significantly reduce the building’s energy costs.

Co2 r744

Thermodynamic Properties of R744 (Carbon Dioxide - CO2) Critical Pressure: 7.377 MPa, Critical Temperature 30.978°C Ideal Gas Constant of Carbon Dioxide: R = 0.1889 kJ/kg.K. CO2 Property Tables: Saturation Properties - Temperature Table (-20°C - 5°C) Saturation Properties - Temperature Table (5°C - 30.978°C) The triple point of carbon dioxide is high and the critical point is low compared to other refrigerants. The chart in Figure 1 shows the triple point and the critical point on a phase diagram. Figure 1: R744/CO2 phase diagram R744 (Carbon dioxyde) R744, or carbon dioxide, is making its re-entry into the industrial refrigeration scene. Once thought to be a wasteful chemical requiring too much high pressure to be feasible as a coolant, environmentalists now hail R744 as an answer to growing concerns.

2015-05-14 The refrigerant is carbon dioxide (CO2), also called R744 in this application. The compressor drives the flow of CO2 through the cycle and raises the pressure above the critical pressure. The gas cooler rejects heat from the high pressure CO2 to the environment.
