Abstract
An efficient indirect building cooling system that bypasses a conventional chiller mechanism by connecting the indoor and outdoor intermediate fluid systems when conditions permit. This system includes indoor and outdoor fluid cooling circuits, each of which interfaces with the conventional chiller mechanism. The two fluid cooling circuits are connected together when weather conditions make doing so more efficient.
Claims17
An improved cooling system including a chiller circuit having at least a compressor, an expansion device, an evaporator and a condenser connected by conduits through which refrigerant is configured to flow, an indoor fluid circuit through which a first cooling fluid is configured to flow, the indoor fluid circuit having at least one heat exchanger that is configured for indoor air to be directed across and for the first cooling fluid to flow through, wherein the first cooling fluid is configured to flow through the evaporator, and an outdoor fluid circuit through which a second cooling fluid is configured to flow, the outdoor fluid circuit having at least one heat exchanger that is configured for outdoor air to be directed across and for the second cooling fluid to flow through, wherein the second cooling fluid is configured to flow through the condenser, the improvement comprising:
- (a) a first fluid conduit extending from fluid communication with the indoor fluid circuit to fluid communication with the outdoor fluid circuit;
- and
- (b) a second fluid conduit extending from fluid communication with the outdoor fluid circuit to fluid communication with the indoor fluid circuit.
A method of cooling a building using a chiller circuit having at least a compressor, an expansion device, an evaporator and a condenser connected by conduits through which refrigerant flows, an indoor fluid circuit through which a first cooling fluid flows, the indoor fluid circuit having at least one heat exchanger that indoor air is directed across and through which the first cooling fluid flows, the first cooling fluid flowing through the evaporator, and an outdoor fluid circuit through which a second cooling fluid flows, the outdoor fluid circuit having at least one heat exchanger that across which outdoor air is directed and through which the second cooling fluid flows, wherein the second cooling fluid flows through the condenser, the method comprising:
- (a) conveying at least some of the first cooling fluid in the indoor fluid circuit to the outdoor fluid circuit;
- and
- (b) conveying at least some of the second cooling fluid in the outdoor fluid circuit to the indoor fluid circuit.
An improved cooling system including a chiller circuit having at least a compressor, an expansion device, an evaporator and a condenser connected by conduits through which refrigerant flows, an indoor fluid circuit through which a first cooling fluid flows, the indoor fluid circuit having at least one heat exchanger across which indoor air is directed and through which the first cooling fluid flows, wherein the first cooling fluid flows through the evaporator, and an outdoor fluid circuit through which a second cooling fluid flows, the outdoor fluid circuit having at least one heat exchanger across which outdoor air is directed and through which the second cooling fluid flows, wherein the second cooling fluid flows through the condenser, the improvement comprising:
- (a) a first fluid conduit extending from fluid communication with the indoor fluid circuit to fluid communication with the outdoor fluid circuit;
- and
- (b) a second fluid conduit extending from fluid communication with the outdoor fluid circuit to fluid communication with the indoor fluid circuit.
