1. High temperature working condition means 40°C/5°C, intermediate temperature means 40°C/-10°C, and low temperature means 40°C/-35°C. With economizer, the liquid outlet temperature is 5°C higher than saturated temperature of make-up pressure. Cooling water inlet temperature of oil cooler is 33 °C and temperature difference of water inlet/outlet is 5°C.
2. Data with "()" is for refrigerant-cooled oil cooler.
