Abstract

A climate control system for a storage unit. The system includes a reverse cycle chiller; a fluid supply line in fluid communication with an outlet of the fluid side heat exchanger; a fluid return line in fluid communication with an inlet of the fluid side heat exchanger and the fluid supply line; at least one hydronic coil in optional fluid communication with the fluid supply line and the fluid return line, the at least one hydronic coil located in a room to be controlled; a controller in communication with the reverse cycle chiller and the at least one hydronic coil; an ambient temperature sensor in communication with the controller; an ambient humidity sensor in communication with the controller; a room temperature sensor in communication with the controller, the room temperature sensor positioned in the room; and a room humidity sensor in communication with the controller, the room humidity sensor positioned in the room. A method of controlling the climate in a storage unit is also described.
