Abstract: A refrigeration system is provided, such as for use with chillers. The system uses a tube-side condenser, such as a microchannel condenser, along with a shell-side evaporator such as a falling film evaporator. A flash tank economizer is disposed between the condenser and the evaporator, and an inlet valve to the flash tank is controlled based upon subcooling of condensate from the condenser. The vapor exiting the flash tank may be fed via an economizer line to a system compressor. Liquid phase refrigerant combined with some gas phase refrigerant exits the flash tank and is directed through an orifice before entering the evaporator.

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 heat exchanger is provided with stacked coil sections. Each of the stacked coil sections is configured to circulate a fluid independent from the other coil section. An air moving device is used to circulate air through both of the stacked coil sections. The stacked coil sections are positioned to have the air exiting the one coil section entering the other coil section.

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.
