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 heating and cooling system includes an evaporator, a compressor, and a condenser. A heat exchanger, which may be an outdoor heat exchanger, is configured to receive the refrigerant from the condenser, to selectively extract heat from or to add heat to the refrigerant, and to transfer the refrigerant to the evaporator. First control valving, disposed between the condenser and the heat exchanger, is configured to regulate flow of the refrigerant from the condenser to the heat exchanger in a first mode of operation. Second control valving, disposed between the condenser and the heat exchanger, is configured to regulate flow of the refrigerant from the heat exchanger to the evaporator in a second mode of operation. The system may be operated in a variety of modes by appropriate control of the valving and other system components.

Abstract: A method is provided including receiving a first input indicative of a desired design capacity of a refrigeration system, and receiving a second input indicative of a desired maximum acoustical noise of the refrigeration system. The method also includes iteratively selecting a candidate compressor system from a set of compressor systems, and iteratively selecting a candidate condenser system from a set of condenser systems. In addition, the method includes simulating operation of the refrigeration system based on the candidate compressor system and the candidate condenser system until a suitable refrigeration system is established having a computed design capacity greater than or equal to the desired design capacity, and a computed maximum acoustical noise less than or equal to the desired maximum acoustical noise. The method further includes providing an output indicative of the candidate compressor system and the candidate condenser system of the suitable refrigeration system.

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 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.
