Can home air heating be suitable for outdoor use at minus 20 degrees Celsius in northern winter?

1. Home air energy heating can be suitable for use in the northern winter at minus 20 degrees, the temperature difference of the working environment of the air energy heat pump at room temperature can operate normally at -7 degrees to 40 degrees, and the ultra-low temperature air energy heat pump can also operate normally at -25 degrees, the low temperature operation standard of the air energy heat pump in the industry is -10 degrees, and the lowest temperature in Shaanxi is minus 10 degrees in winter, and the air energy heat pump heating can operate normally in Shaanxi.

2. Principle: The working principle of air energy heat pump, through the reverse Carnot principle of heat pump, absorbs a large amount of low-temperature heat energy in the air with very little electrical energy, and turns it into high-temperature heat energy through the compression of the compressor to achieve the purpose of air energy heating. Therefore, the amount of heat in the air directly affects the energy efficiency of the air energy heat pump unit, and the amount of heat in the air is the most intuitive embodiment of the temperature of the air.

3. The influence of ambient temperature on the working performance of air energy heat pumps: China's heating areas are divided into severe cold zones, cold zones, subarctic zones and normal temperature zones from north to south, so the influence of different ambient temperatures on the working performance of air energy heat pumps is also different.

At present, air energy water heaters are divided into household machines and commercial machines, according to the way of work, they are divided into direct heating type, circulation type, split direct heating type, the first generation is direct heating type, cold water directly enters the host to heat up to 55 degrees of hot water and then sends it to the thermal insulation water tank for preservation, and the hot water comes out from under the water tank. The second generation is circulation, after the cold water directly enters the thermal insulation water tank, the water is pulled back to the main engine for heat exchange heating by the circulating pump, and then sent back to the water tank, heated in layers, and the hot water goes out from below. The third generation is the split direct heating type of air energy water heater, and the cold water directly enters the insulated water tank and directly exchanges heat with the heat exchanger in the water tank for heating, and the hot water goes out from above.

Air energy heating has ultra-low temperature, it can operate normally in a low temperature environment of minus 25, which can meet the heating needs of most areas in the north. Therefore, northern heating is also suitable for air energy heating.

Air energy heaters.

Pay attention to the transition of fire prevention, winter is closer to us, the weather is colder, especially in some cities in the north, the temperature in winter can be described as cold and biting, people often use central heating, air conditioning, electric blankets, coal stoves and other heating to resist the cold, but while enjoying the warm spring, we must also pay attention to some matters. <>

Precautions when heating: (1) The switch on the heating pipe in the home cannot be switched at will. When the heating system is running for the first time, it usually needs to be commissioned. Specifically, it is to adjust the position of each standpipe valve, open the manual venting valve of each radiator to remove the air accumulated on the radiator, or open the venting valve of the gas collection tank installed on the top of the system until each radiator is heated.

2) When approaching the hot air sheet, the room should try to maintain a certain heat dissipation, and no sundries should be stacked on or in front of the hot air sheet, so as not to affect its heat dissipation effect. The furnace space cannot be changed at will. The installation position of the heater is conducive to indoor heating, ensuring that the air convection and indoor temperature are relatively even, once the position changes, it will lead to an imbalance in the indoor temperature.

In addition, once the pipes and radiators are moved, they are prone to leakage, causing unnecessary losses. It is not allowed to release water from the pipeline arbitrarily, when there is no hot water in the pipeline, cold water should be supplemented to keep the pipeline system at a certain pressure, the more water is discharged, the lower the water temperature in the pipeline, and the lower the indoor temperature. <>

There are several issues that should be paid attention to when using central heating. First, the radiator should maintain a good heat dissipation space around it, and too many sundries can not be piled up, and the radiator cannot be sealed during decoration, so as not to affect the quality of heating. Clause.

2. The various valves on the heating pipe, after debugging, cannot change the position and close or open at will. Clause.

3. The doors and windows of the heating room should be well sealed, and the walls leading to the balcony should not be broken at will. Clause.

Fourth, after the start of heating, a period of "heat storage" is needed to meet the qualified temperature of each household. Clause.

Fifth, the heating design and installation must have professional and technical requirements, in the interior house decoration, can not disassemble the heating equipment or increase the heating equipment at will, nor can the installation position of the radiator be changed. <>

Northern families should pay attention to fire prevention when heating.

When the heating is not started, prepare thick clothes, cotton jackets and pants, prepare thick quilts (duvets and other warm ones), pay attention to seal the doors and windows, and the windows can be glued with tape. When heating: It's best to stay at home.

Nowadays, many northern families no longer use coal for heating, but direct radiator heating, and the main thing in the process of use is to check the heating effect of radiators.

Attention should be paid to the safety of heating, when it is time to turn on the heating, if you want to burn coal, you must be careful, you must be careful to burn to prevent fire, and open windows for ventilation to prevent carbon dioxide poisoning.
