　　What is the reason for the increase in exhaust temperature of the heater chiller?

　　1. Poor heat dissipation of the heater cooler: The heater cooler is an important component that cools the refrigerant from a gaseous state to a liquid state. If the condenser has poor heat dissipation, it can cause the exhaust temperature to be too high. Therefore, it is necessary to regularly clean the condenser to maintain its heat dissipation effect.

　　2. Insufficient area of heater and cooler: If the area of heater and cooler is insufficient, it will lead to poor heat dissipation and high exhaust temperature. Therefore, it is necessary to select a suitable condenser based on the specifications and usage requirements of the equipment to ensure its sufficient area.

　　3. Heater cooler fan malfunction: If the heater cooler fan malfunctions, it can lead to poor heat dissipation and high exhaust temperature. Therefore, it is necessary to regularly check the operating condition of the condenser fan and promptly repair or replace the faulty condenser fan.

　　4. Internal fault of compressor: if the compressor of the water chiller has internal fault, such as Wastegate, compressor piston and other faults, the exhaust temperature will be too high. Therefore, it is necessary to regularly check the operating condition of the compressor and promptly repair or replace faulty components.

　　5. Insufficient refrigerant: If the refrigerant of the chiller is insufficient, it will lead to excessive working load of the compressor and high exhaust temperature. Therefore, it is necessary to regularly check the filling amount of refrigerant to ensure its adequacy.

　　How to adjust?

　　1. Improving environmental ventilation conditions, the lubricating oil level in the heater cooler is too low.

　　2. The oil cooler is dirty and requires dust and scale removal treatment.

　　3. The oil filter core is blocked and needs to be replaced.

　　4. Temperature control valve malfunction (faulty component), clean or replace.

　　5. Fan motor failure; The cooling fan is damaged.

　　6. The exhaust duct is not smooth or the exhaust resistance (back pressure) is high.

　　7. If the ambient temperature exceeds the specified range (38 ℃ or 46 ℃), is the pressure gauge faulty.
