Equipment and people will be ill, the refrigeration heating temperature control system Xiaobian tells you that some common faults everyone must know the reason! Outflow protection Failure analysis: 1. Whether the actual temperature of the water tank exceeds the set temperature; 2. The tank sensor is not placed correctly or the tank sensor is not in close contact with the blind tube wall. 3, the water tank temperature sensor connection disconnection or temperature sensor resistance drift. High voltage protection Failure analysis: Confirm that the high pressure of the system is too high by the pressure gauge, then the waterway is faulty: 1. The actual flow rate of the circulating water pump is too small. 2. The valve or filter in the waterway is blocked. 3. The valve is not fully open. 4. The water temperature setting is too high. 5. The heat exchanger is fouled and blocked. 6. There is air in the water system. 7. Water shortage in the water system. After confirming that the system high pressure does not reach the alarm pressure through the pressure gauge, check whether the pressure switch wiring is reliable, and re-plug the wiring plug reliably. After the machine is stopped, use the meter to check whether the high pressure switch is turned on. If it is not turned on, the pressure switch may be broken. Exhaust temperature is too high protection Failure analysis: 1. When the unit is running, check whether the exhaust temperature exceeds 120 °C: the exhaust temperature is not high, the exhaust temperature sensor may be bad, the contact is bad, or the board is damaged. 2. If the exhaust temperature is too high, check whether the high and low pressure are normal, whether the expansion valve is slightly blocked or the refrigerant is slightly leaking (there is generally oil stain at the leak point), which is good for the refrigeration heating temperature control system , and if necessary, replace it. Expansion valve or re-welding. Water level switch failure Failure analysis: 1. The high and low water levels are reversed. 2. Poor contact in low water level equipment. 3. The motherboard is faulty. The host is not running Failure analysis: 1, power failure - find out the reasons to solve the power problem 2, the compressor contactor is broken - replace the contactor 3, the wiring is loose - tighten the loose point 4, compressor overheat protection - find out the cause of heat after booting 5, insufficient water flow - cleaning the filter, discharging air, etc. The unit's heating capacity is low Failure analysis: 1. Bad heat dissipation of air heat exchanger - cleaning air heat exchanger 2, insufficient water flow - cleaning filter 3. Insufficient refrigerant injection amount - leak detection and injection of quantitative working fluid 4. The fan motor is broken and the evaporator is frosted seriously. Defrost is not clean Failure analysis: 1. The coil probe is off, and the refrigeration heating temperature control system Xiaobian tells everyone to check whether the temperature position of the coil probe is accurate and damaged. 2. The defrosting parameter setting is not accurate, and the defrosting parameters are re-adjusted. 3. The system lacks refrigerant. Fan does not turn Failure analysis: 1. The fan fastening screw is loose - tighten the loose screw 2, the fan motor burned - replace or repair the fan 3, the contactor is bad - replace the contactor 4, the fan capacitor is bad - replace the capacitor Knowledge of these faults, the refrigeration heating temperature control system Xiaobian believe that everyone can deal with it when encountering a fault!
