Mirage HVAC – Windings.

Because of this, it is necessary that the compressor which is used in a heat pump equipment is designed so that:  The motor windings are prepared to withstand higher temperatures than usual. The protective elements of these windings must be adequate.

The oil used to lubricate the compressor must be adequate to withstand the high temperatures that will look without suffering chemical transformations. The lubrication must be secured for any operating condition, ensuring the life of all moving parts and bearings, valves, adjustable valve, check valves, etc.. 

The coolant should be maintained at an appropriate level cycle, both in summer and winter to prevent slugging the compressor. Today, thanks to tests performed on the operating conditions of a heat pump can provide hermetic compressors specially designed to work in heat pump equipment. 

Also used in this type of mineral based compressor oils,  that prevent many of problems,  that arise when using estándar. Consequently considered refrigeration oils, these improvements can extend the area of ​​operation.
