ENVIRONMENTAL CONTROL SYSTEM

摘要

"ENVIRONMENTAL CONTROL SYSTEM" An environmental control system 1 has an evaporator section comprising an evaporator 2 for extracting heat from (and dehumidifying) air destined for the controlled space or for exhaust - this air may be a controlled mixture of fresh and recycled air and a chiller 3 for extracting heat from a source 20 such as well water and from a thermal store 12. The heat pump condenser section comprises a condenser 10 for rejecting heat to air entering the space and a condenser receiver 11 for rejecting heat to the store 12. The system includes a system controller (not shown) programmed to control operation in a manner tending to minimize the prime energy requirement.
