WebFeb 6, 2006 · When the condensing temperature is high, the compressor must compress the refrigerant from the low-side (evaporating) pressure to an elevated high-side (condensing) pressure. This added work done by the compressor would raise the heat of compression. Thus, the compressor's discharge temperature will be higher. WebAug 20, 2024 · Under high pressure the refrigerant remains in its liquid state, and when the pressure is reduced the liquid refrigerant begins to ‘boil’ and change in to a vapour or gas. …
