ABSTRACT:
A system is described for controlling the air and radiant temperature, ventilation, and humidity within an enclosed building. The system heats or cools air drawn through the ground and introduced into a conduit disposed below the frost line where it is drawn into the interior of the building. The air is circulated through the building where it may be either heated or cooled and then exhausted. Apparatus is provided for either recovering and storing heat from or transferring excess heat to the exhausted air. The apparatus comprises a tank for storing a first heat absorbing fluid, a compressor for compressing a second heat exchange fluid, a heat exchanger for transferring heat from air leaving the interior of the building to the second fluid when heat is to be stored (or transferring from the second fluid to air leaving the interior of the enclosure when heat is to be released from the system). The apparatus also includes a reversible heat pump and conduit means for circulating the second fluid among the tank, compressor, and heat exchanger in a direction depending on the mode of operation. The conduit means includes a coil disposed in the tank for transferring heat between the first and second fluids so that in one mode of operation it functions as a condenser when heat is stored in a tank and in a second mode as an evaporator when heat is to be released from the system.
