Practice 2: The CT, ET and TR are the same as Practice 1 except the liquid is subcooled to 20ºF using ET temperature of 20ºF which is same as the main ET of 20ºF. ESIE15 05 R32 service manual R32 lacks compatibility with mineral oil (SUNISO) and reduces oil return performance, so to ensure compatibility ether oil (a synthetic oil) has been selected as the refrigerant oil for R32 units. Ether oil is thus used as the refrigerant oil for both R32 and R410A units, but product names are different as indicated in the table below. Drop‐in Performance of Low GWP Refrigerants in a Heat Pump ... Will R32 and R1234yf work for existing air‐source heat pump systems? Approach Drop‐in tests Determine refrigerants charge to be used in the system without any change in the system components Measure energy performance and capacityof R32 and R1234yf with respect to R410A. R32 pressor for Air conditioning and Refrigeration ... Figure 1: PH Diagram parison R32 v.s. R410A at ARI Condition As the diagram shows, in theory, R32 has 11% higher capacity and 3% higher efficiency at ARI rated condition. The relative gains will be increased when the Te (Saturated Evaporating Temperature) and the Tc (Saturated Condensing Temperature) is getting higher. 2.1 The pressure enthalpy diagram SWEP The pressure enthalpy diagram (log P h diagram) is a very useful tool for refrigerant technicians. First, an explanation of how the diagram is built up is given, and then its use is describ ed. Figure 2.1 shows the principle of a log P h diagram, and indicates the refrigerant's various thermodynamic states. The Pressure Enthalpy Chart The pressure enthalpy chart, as shown in Fig. 2, displays all the pertinent properties for a given refrigerant (in this example R22). The bubble to the left is the portion of the diagram where the refrigerant is in the saturated condition. The blue line on the left of the bubble represents the 100% saturated liquid line, Appendix B Log P h diagrams for refrigerants SWEP Appendix B Log P h diagrams for refrigerants Experts in brazed plate heat exchangers SWEP is a world leading supplier of brazed plate heat exchangers for HVAC and industrial applications. refrigerant selection with Mollier Chart PH Diagram Actually it is log Pressure versus Enthalpy [ Up ] [ MollierChart ] [ CoolTime ] If you need to compare the performance of refrigerants, this program will suit your needs. It is very easy to use and gives the basic cycle performance both graphically and in text form. The Pressure Enthalpy Chart refrigeration system can be plotted on the P H diagram. Lets assume our system is operating at a 20ºF evaporator and 100ºF condensing. The saturated vapor entering the compressor suction would be at 20ºF, illustrated by point #1 in Fig. 3.

Performance Measurement of R32 Vapor Injection Heat Pump ... in residential air conditioning and heat pump systems. A potential substitute for R410A is R32, which has a GWP of 675. This paper investigates the performance difference of R410A and R32 in a vapor injected heat pump system. A drop in test was performed using R32 in a heat pump system that was designed for R410A, for both cooling and Solstice® N40 (R 448A) | European Refrigerants Zeotropic blend designed to serve as a replacement for R 404A in supermarket refrigeration retrofits or new systems.
