Principle of operation
We knew the principle of "DX" (the evaporator of the refrigerating machine directly cools the air in the chamber air handler). This time, we realize the direct expansion in each room because the coolant is transported to the interchange of premises used evaporator! It is neither air nor water flowing through the pipes, but the refrigerant.
From an outdoor unit, it can power up to 32 indoor units. Outside groups available on the market today have cold powers ranging from 15 to 90 kW in compact for connecting an independent refrigerant circuit. These can be multiplied, provided that the space available for outside groups are present. But these are facilities that will then operate in parallel (no exchange between circuits connected to different outdoor units).
This system can operate in three diet:
* Operation in cooling only
* Reversing mode (cold or hot)
* A heat recovery (hot and cold simultaneously)
In the outdoor unit is a variable speed hermetic compressor (scroll compressor or rotary compressor), with a regulation "INVERTER", ie variable speed by adjusting the supply frequency. allowed to quit a good control of flow rates of fluids and good mastery of electricity especially in the summer or the need for electrical energy is increased [
