Blink of an eye into the coldest month of the year, but for the South's friends, there is always the need to buy some heating appliances in the winter without heating.As the most commonly used heating appliances, air conditioners and electric heaters are hot in the winter market Of the two types of appliances, then, today we come to analyze the following, air conditioning and heater which is better.
Air conditioning more power
Heater principle is electric wire, Joule law of junior high school physics, consumption of 1KW of electricity to create 1KW of heat. The principle of air-conditioning is a heat pump, a complete thermodynamic cycle. Air conditioning and cooling, the power consumption of W-driven compressor, from The room to remove part of the heat Q, released to the atmospheric heat Q + W. Air conditioning heating, the power consumption W drive compressor, remove some of the heat Q from the atmosphere, released to the room heat Q + W. 1.5 HVAC For example, the general heating power is 1KW and the heating capacity is 3000KW without power-assisted heating, which means that 1KW of electricity can generate 3KW of heat, which shows that the air conditioner is more efficient and produces the same The heat, air conditioning more power.
Electric heating applications more occasions
Air conditioning is generally installed in the house very close to the location, and people are in the lower position, the hot air is relatively light, which resulted in the housing is very warm in the upper part, but where the height is still cool. The heater is generally placed on the ground, the more prone to heat convection, so that houses more uniform heating. Air conditioning, wind, electric heater is not the wind, the same temperature environment, the wind will make people feel colder, that air conditioning would like to achieve Heaters the same effect, then create a higher room temperature.
Residents of the Yangtze River Basin in winter to air-conditioning heating, good home conditions can be low-temperature radiant floor heating. Without low-temperature radiation heating also want to ensure indoor comfort, you can air-conditioning heating + electric heater heating, complement each other.
If the room is sealed or air conditioning is more efficient, long-term use of air conditioning is recommended. Although the air conditioning power is large, but reached the set temperature on standby operation.But need to be aware that the long-term use of these two heating products have a drawback, Need to humidify the indoor air in time, otherwise it will sharply reduce the indoor humidity is not conducive to people's lives and health.
