Common room heating equipment in winter includes an air energy heat pump, air conditioner, wall-mounted furnace, electric heater, etc.
The whole house is selected for heating, represented by the heating air conditioner, gas wall-mounted furnace, air energy heat pump, etc. The advantages of heating air conditioners are that the air outlet is violent and the temperature rises quickly, but the comfort of heating is poor, the heating energy consumption of the air conditioner is very high and the thermal efficiency is low. The wall-mounted boiler is the abbreviation of a gas wall-mounted boiler. It is a water heater using natural gas as energy. It can save 20%~28% on gas costs when used with an indoor temperature controller. An Air energy heat pump is a device that makes use of high-position energy to make heat flow from low position heat source air to high position heat source. Compared with electric heating and gas heating, it is more energy-saving and has lower costs. Its disadvantage is that the cost of purchasing a machine is relatively high.
For local heating, electric heaters such as air heaters, oil heaters, and "small sun" are representative. Electric heaters are widely used in residential buildings, offices, hotels, shopping malls, hospitals, schools, train carriages and other mobile heating, simple movable houses, and other civil and public buildings. Among them, oil-fired heaters have relatively good safety and thermal insulation and are popular space heaters in recent years.
Selection and Use Guide
1. The power of the wall-mounted stove should be selected according to the living area of the family, so as to save gas and achieve environmental protection while ensuring heating.
2. The fan heater can select PTC ceramic electric heating element, which has higher efficiency and lower temperature attenuation; It is better to have filter cotton at the air inlet of the air heater to avoid dust fluff entering and causing faults and dangers; At the same time, regular cleaning shall be carried out.
3. The heating equipment with a metal shell shall have a three-phase plug to ensure safe use; Many heating equipment have large power, and the electrical appliances with more than 2200W should be replaced with 16A sockets, and should not be used on the same socket with other electrical appliances.
4. When using the "Little Sun" heater, pay attention not to stare at it for a long time, which may damage the fundus of the eye and cause vision loss.
5. The oil heater will still retain a certain temperature after shutdown, and the accidental dumping of the machine may cause safety problems that need attention.
