WebMay 15, 2014 · The basic transcritical CO2 systems exhibit low energy efficiency due to their large throttling loss. Replacing the throttle valve with an ejector is an effective measure for recovering some of the energy lost in the expansion process. In this paper, a thermodynamic model of the ejector-expansion transcritical CO2 refrigeration cycle is … WebFeb 12, 2024 · Its temperature and pressure rise in the compressor, and it moves to the condenser coils to reject its heat outside. A heat pump reversing valve simply reverses the process by cycling the refrigerant the opposite way. It makes the condenser function as the evaporator and vice versa. You can see the heating cycle in the image below.
WebA suction pressure low superheat condition occurs when the capacity regulator is large because of which it feeds in more refrigerant into the coils of the evaporator as the heat load is not enough for the available refrigerant. Another possible reason for this condition could be the high capacity of the thermal expansion valve. Web2. Typical low pressure or suction side pressure for R410A is about 120 psi, varying by ambient temperature, here assuming 75°F, may vary by equipment and metering controls. 3. Typical high side pressure for R410A is < 600 psi at an ambient outdoor temperature of 95 °F, may vary by equipment. 4.
