Frequent frosting of Chigo air conditioners is a normal phenomenon because of frequent frosting in outdoor units. In order to maintain the heating effect, the air conditioner should be defrosted frequently.
Due to the continuous low temperature of the weather, when the outdoor temperature is lower than 0 degrees, there will be frequent defrosting, generally the air conditioner defrosts once in about 45 minutes, and each defrosting time is about 10-15 minutes, and the frosting situation will be more frequent in rainy and snowy weather. This situation can only give the air conditioner a break.
Extended Information:
Generally, air conditioners are equipped with a defrost circuit, for heat pump type air conditioners in winter heating work, the surface temperature of the evaporator will reach below zero, the surface of the evaporator may be frosted, thick frost layer will cause air flow to be blocked, affecting the heating capacity of the air conditioner, so there is a defrost circuit on the air conditioner.
The defrost controller is also an electric switch that uses temperature control contact action, and it is a special thermostat that removes the frost layer of the outdoor unit heat exchanger coil during heat pump heating.
Its defrosting method is generally reverse circulation ring thermal defrosting, that is, through the on-off of the contact of the defrost controller switch, so that the electromagnetic reversing valve reversing to achieve the effect of defrosting.
First, household air conditioners mainly use bellows type, differential pressure gauge, electronic defrosting controller these three ways to defrost.
The first kind of bellows type defrosting tube temperature package attached to the surface of the evaporator, when the temperature reaches 0 degrees, the power supply of the coil of the reversing valve is cut off, the air conditioner is changed to external heating operation, so that the surface temperature of the external evaporator rises, to achieve the effect of defrosting, when the surface temperature of the evaporator reaches 6 degrees, the power supply of the coil of the reversing valve is turned on again, and the indoor heating state is restored, and during the defrosting period, the fan of the indoor unit stops.
The second differential pressure meter defrosting controller. It uses a differential pressure gauge to feel the pressure difference before and after frosting in the outdoor unit to control itself.
The high pressure of the differential pressure meter defrost controller is connected to the air inlet side of the outdoor evaporator surface, and the low pressure is connected to the air outlet side of the outdoor evaporator surface. After the outdoor evaporator frosts, the airflow resistance increases, and the pressure difference between the front and rear changes, so that the defrosting circuit is turned on, so that the electromagnetic power is cut off and the defrost is turned.
The third electronic defrosting controller controls the defrosting circuit through two parameters, temperature and time. It first senses the temperature of the surface of the evaporator of the outdoor unit through a thermistor, and controls the electromagnetic directional valve, and controls the time of defrosting through an integrated circuit
Second, 6 phenomena when air conditioning is defrosted.
The first phenomenon is that the outdoor unit drips.
The second phenomenon is that the outdoor unit emits hot gas.
The third phenomenon is that the indoor unit stops blowing hot air.
The fourth phenomenon is frosting in the heat exchanger inside the indoor unit.
The fifth phenomenon is that the indoor unit shows a sharp drop in temperature.
The sixth phenomenon is that the air conditioner stops heating.
After the defrosting is over, the outdoor unit no longer drips water and no longer emits hot steam; The indoor unit resumed blowing hot air, and the frost also melted, indicating that the temperature gradually rose, and the air conditioner heated up again. And so on and so forth.
At present, household air conditioners have a strong lineup of 3 categories, window type, wall-mounted type, and vertical cabinet type, and multiple varieties and specifications.
Central air conditioning has more than ten series such as CMV intelligent inverter multi-connected central air conditioning, CMD intelligent multi-connected central air conditioning, air-cooled module unit, screw water-cooled chiller, water-source heat pump unit, ground-source heat pump unit, air-source heat pump water heater unit, ceiling machine, air duct machine, crane, air-cooled cabinet machine, water-cooled cabinet machine, etc.
At the same time, Chigo Small Household Appliances Division is positioned as the main kitchen appliances, including range hoods, gas stoves, disinfection cabinets, electric water heaters, and household electrical appliances including induction cookers, full nutrition grain multi-function machines, rice cookers, electric pressure cookers, electric kettles, etc.
