Does the heater cost electricity or the air conditioner costs electricity?

When the household air conditioner heats, the refrigerant of the outdoor unit is pressurized by the compressor into high-temperature and high-pressure gas, which enters the heat exchanger of the indoor unit (at this time, the condenser), condenses, liquefies and releases heat, becomes liquid, and at the same time heats the indoor air, thus achieving the ultimate goal of increasing the indoor temperature. Air heater is a combined device consisting of ventilator, motor and radiator. Suitable for all kinds of workshops where air can be recycled. When the air contains no dust and combustible gas, it can be used as circulating air for heating.

Air heater is mainly composed of air heater and fan. The air heater radiates heat, which is then sent out by the fan, thus adjusting the indoor air temperature. The energy efficiency ratio of air heater is less than half of that of constant speed air conditioner with the same power and less than one third of that of variable frequency air conditioner with the same power.

Does the heater cost electricity or the air conditioner costs electricity?

First, the energy efficiency ratio of heater and air conditioner.

The energy efficiency ratio of (1) air heater is 1: 1, power consumption 1000 watts, and heat generation 1000 watts.

(2) Energy efficiency ratio of air conditioner 1:3, power consumption 1000 watts, and heat generation of 3000 watts.

(3) In terms of generating the same amount of heat, the power consumption of heaters is three times that of air conditioners.

Second, different room areas consume different amounts of electricity.

1. If the room is less than or equal to 20 square meters, the heater will save electricity.

(1) heater: suitable for heaters with power of 1800 watts.

(2) Air conditioning: It is suitable for two air conditioners, with heating power 1800 w+ auxiliary electric heating power1500 w = 3300 w..

(3) For a room of 20 square meters, the heater of 1800w is just right, and the power consumption of air conditioning is far greater than that of the heater.

Air conditioning saves electricity in rooms over 2.20 square meters.

(1) The air conditioner has a high energy efficiency ratio. Two air conditioners consume 3300 watts to generate 1800*3+ 1500=6900 watts of heat, which can raise the temperature of the whole room to 20 degrees.

(2) The heater is low in energy efficiency, suitable for local heating, and has little effect on raising the temperature of the whole room. Even if you use a 3300-watt heater and heater, you can only generate 3300 watts of heat, which is less than half of the same power air conditioner.

(30) If the area is more than 20 square meters, please use air conditioner for heating. Air conditioner consumes the same amount of electricity as heater and generates three times as much heat as heater.

Third, heaters and air conditioners are suitable for different families.

(1) The air conditioner can be used in time switch machine, and the temperature rises quickly, so it is more suitable for families whose heating time is not fixed, but needs a certain length of time, and the space is well sealed.

(2) It is suitable for small apartments or rooms, with small occupied space, convenient movement and simple installation. Don't use the heater if your household appliances are unstable or the electricity bill is high.
