You can see that this R410A pressure chart includes high and low side pressures at temperatures ranging from -60 °F to 155 °F. Higher temperature equates to higher pressure. Here are 4 examples of how you can use this chart: In the heating mode, the R410A and R32 multi-heat pumps with vapor injection showed 7.5%–13.9% higher heating capacity than those without vapor injection, while showing 2.6%–7.0% and 1.1%–4.7% higher COPs, respectively. ... Roh et al. [12] applied an additional expansion valve to a heat pump to control the intermediate … · One for heating and one for cooling. At a given outdoor ambient, indoor wetbulb and dry bulb, the suction and discharge pressures should intersect on a graph at specific temp readings along a curve on the graph. Also, as Houston said, there should be a desired subcooling reading at the outdoor unit.The higher the COP of a heat pump, the greater the percentage of "free" heat in its total output. Water-to-water heat pumps connected to geothermal sources and low temperature (95¯-120¯F) loads typically have COPs in the range of 2.5 to 3.2. Technology improvements continue to produce incremental gains in COP. Formula 2.
