The best HVAC designs are only as good as the level of comfort they provide. Here the Hybrid Systems once again excels, making cooling available year round through an ultra quit, high efficiency rotary compressor. The compressors are connected through a refrigeration piping system to a standard cooling coil. The heat removed from the air is rejected from the unit into the water loop via a simple condenser. Loop temperatures scheduled to outdoor air temperatures ensure that the cooling cycle operates at its highest efficiency levels as the cooling load increases, providing comfort inside, regardless of what is happening outside.
