The compressor overload protection will trip, which means that the system high voltage or overheating current is too high.
Causes and elimination of high pressure, high temperature and overheating;
1, too much refrigerant. Reduce the amount of refrigerant appropriately.
2. Poor heat dissipation. Check the condenser tube for dirt and clean the condenser.
The pipeline system is blocked. Refer to the pressure gauge to judge, eliminate and reprocess the system.
4. Evaporator or filter screen accumulates dust and scale. The air flow becomes smaller, the system pressure and temperature are unstable, and the evaporator or filter screen is cleaned.
5. Fluorine deficiency is also possible. When fluorine is lacking, the exhaust temperature of the compressor will overheat, which will trip the overheat load protection switch.
The problem with the circuit is:
1, control circuit board failure.
2. The temperature sensor is overloaded and the information is wrong.
3. Loose power cord and poor contact.
4. The starting capacitor or compressor starting coil is burnt out.
There is not enough information, so we can only analyze it in this way, and there are many other possibilities.
It is recommended to find a professional maintenance person to check it.
Air conditioning is air conditioning. It refers to the process of adjusting and controlling the temperature, humidity, cleanliness, speed and other parameters of the ambient air in the building/structure by manual means.
Generally, it includes cold source/heat source equipment, cold and hot medium transmission and distribution system, terminal device and other auxiliary equipment. It mainly includes water pump, fan and pipeline system. The terminal equipment is responsible for the specific treatment of air and temperature by using the cold heat from transmission and distribution, so that the air parameters of the target environment can meet the requirements.
The original air conditioners and refrigerators used toxic gases such as ammonia and methyl chloride. The leakage of this gas will lead to a major accident. Thomas Midgley invented chlorofluorocarbon gas in 1928 and named it Freon. This refrigerant is much safer for human beings, but it is harmful to the atmospheric ozone layer. Freon is the trademark of CFC, HCFC or HFC refrigerants from DuPont, in which the name of each refrigerant also includes a number to indicate the molecular composition of its components (for example, R- 1 1, R- 12, R-22, R- 134). Among them, R-22 HCFC refrigerant, which is widely used in the field of direct evaporative moderate cooling products, will stop being used in newly produced equipment from 20 10 and will be completely stopped in 2020. R- 1 1 and R- 12 have been discontinued in the United States. As substitutes, some refrigerants harmless to the ozone layer have been put into use, including the refrigerant R-4 10A with the trade name "Puron". New environmental protection refrigerants R290 and R32 are gradually entering the market. R290 only contains carbon and hydrogen, but does not contain chlorine and fluorine, and its ozone destruction potential (ODP) is zero.
