In contrast du Reversible air conditioner, The functions of a conventional air conditioning and refrigerator are identical. They take all 2 heat from the ambient air to expel outside. Ambient air is captured either in the room to be conditioned or inside the refrigerator and the exhaust air is out of the room or behind the refrigerator.
It is through the intermediary of a refrigerant to the thermal properties such as specific heat exchanges are allowed.
In the case of a Reversible air conditioner, the circuit is reversed : heat from the outside is taken to be returned to the interior of the room.
The principle of operation of a reversible air conditioner is the same as that of a heat pump. The reversible heat pump air-water or water-water and Reversible air conditioner are 2 reversible systems that produce hot and cold.
Benefits of a reversible air conditioner
This is an economical heating system.
The refrigeration cycle of the air conditioner is simplified, it works with a favorable energy balance : for 1 KW absorbed by the compressor, the air conditioner product 2 KW cold but returns 3 KW heat.
The heat from outside air drawn in winter is multiplied by being released into the workpiece.
However, The COP, ie the coefficient of performance that allows for 1KW absorbed to recover 3, is a function of outside temperature course.
By focusing 2 features hot and cold (instead of in the case of a conventional air conditioning), the gain is evident not only from a financial point of view but also in terms of space occupied.
Disadvantages of a reversible air conditioner
1)The limits of power for the heating function.
No problem if the needs are modest. And revenge, more than the outside temperature is low, the higher the yield will decrease. That's why when large drops in temperature or in areas often exposed to cold, it is advisable to use an auxiliary heater and air conditioner properly handle its reversible. This does not pose a problem. The electronic heat is possible in the 10th grade on an air conditioning.
2)Noise
Even if they are more acceptable than those caused by a mobile air, the noise heard is that of a refrigerator. However, manufacturers are gradually improving their products to make them quieter.
The installation of the outdoor unit on a wall is not aesthetically, always the best effect.
The cost of an air conditioning system is reversible 10 to 20% higher than that of a cold air only.
The heat blast can cause discomfort and gene.
In brief, reversible if the air conditioner split is very suitable for use on a professional rather, he is more reserved for the off season in domestic households for performance reasons but also feelings of discomfort due to air movement.
