Abstract: A modular water based heating and cooling system for providing chilled or heated water to terminal devices in a building to heat/cool individual zones in the building. The system includes a flow control device in fluid communication with a riser chilled water supply line, a riser chilled water return line, a riser heated water supply line, and a riser heated water return line. The flow control device includes first control valves and second control valves. Terminal device supply lines extend from the flow control device and are connected to respective first control valves. Terminal device return lines extend from the flow control device and are connected to respective second control valves. The first control valves and the second control valves cooperate to supply required chilled water or heated water through the terminal device supply lines to terminal devices based on the cooling/heating requirements of the terminal devices.

Abstract: A method for controlling an economizer circuit is provided. The economizer circuit includes a valve to regulate refrigerant flow between the economizer and the compressor. The valve can be opened to engage the economizer circuit or closed to disengage the economizer circuit based on the output frequency provided to the compressor motor by a variable speed drive and an operating condition of the economizer.

Abstract: A system for cooling air for use with a liquid cooling fluid loop. The system includes a first refrigerant circuit with an air-cooled condenser, a second refrigerant circuit with a liquid-cooled condenser, and a free-cooling loop. A control device is provided for controlling the operation of the system between a first mode, a second mode, and a third mode. When operating in the first mode, only the free-cooling loop cooperates directly with liquid cooling fluid in the liquid cooling fluid loop to cool the liquid cooling fluid, when operating in the second mode, the second refrigerant circuit is not engaged, and when operating in the third mode, the free-cooling loop interacts with the second refrigerant circuit to reject heat of the second refrigerant circuit through the free-cooling loop.
