WebJan 10, 2024 · Jan. 10, 2024. The high-pressure fault of the chiller means that the compressor exhaust pressure is too high, which causes the high-pressure protection relay to operate. The compressor discharge pressure reflects the condensing pressure. The normal value should be 1.4 ~ 1.8MPa, and the protection value setting is recommended … WebGeothermal Heat Pump System In principle, a geothermal heat pump functions like a conventional heat pump, by using high-pressure refrigerant to capture and move heat between indoors and out. The difference is that conventional systems gather their heat—and get rid of it—through the outside air.
