Home electric air conditioner and heater which is better?

Has blink of an eye into the coldest month of the night, but for southern friends, there is always a need to buy some warm appliances without heating in winter. As the most commonly used heating appliances, air conditioners and heaters are selling two types of appliances in the winter market, then, today we come to analyze the following, air conditioning and heater which is better.

Air conditioning more power

The principle of the heater is the electric wire, Joule's law of junior high school physics, consumption of 1KW of electricity to create 1KW of heat. The principle of air conditioning is heat pump, a complete thermodynamic cycle. When air conditioning and cooling, power consumption W drives the compressor, removing a portion of the heat Q from the room and releasing it to atmospheric heat Q + W. Air-conditioning heating, power consumption W drives the compressor, remove some of the heat Q from the atmosphere, released to the room heat Q + W. To 1.5 hp air conditioning, for example, do not open the electric auxiliary heat conditions, the general heating power is 1kw, heating 3000kw. That is to say consume 1KW of electricity, can produce 3KW of heat. This shows that air conditioning is more efficient, so produce the same heat, air conditioning more power.

Electric heating applications more occasions

Air conditioners are generally installed in the very upper position of the house, and people are in the lower position, the hot air is relatively light, which resulted in the upper part of the house is very warm, but the height where people are still cool. The heater is generally on the ground, more prone to heat convection, so that houses more uniform temperature. Windy air conditioners, electric heaters do not have the wind, the same temperature environment, the wind will make people feel colder, that is to say the air conditioner to achieve the same effect of the heater, it should create a higher room temperature.

Residents of the Yangtze River Basin in winter to air-conditioned heating, good home conditions can be low-temperature radiant floor heating. No 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 recommended. Although the air conditioning power, but reached the set temperature on standby operation. However, it should be noted that long-term use of these two heating products has a drawback. It is necessary to humidify the indoor air in time, otherwise indoor humidity will be drastically reduced, which is detrimental to people's life and health.
