Vapor compression refrigerant system with secondary modulating heat transfer

Abstract

A vapor compression refrigeration system having an air dehumidifying system and a heat transfer system. The dehumidifying system has a refrigerant circuit and an air circulating system transporting air from an enclosed space at least partly through the refrigerant circuit and back to the enclosed space. The refrigerant circuit carries a phase change refrigerant which picks up heat from the air passing through the air circulating system. The heat transfer system carries a fluid that will not freeze below the ambient temperature. A heat exchanger connects the refrigerant circuit to the heat transfer system to pass heat from the phase change refrigerant in the refrigerant circuit to the fluid in the heat transfer system. At least one heat removal unit in the heat transfer system to remove heat from the fluid.
