Abstract: A refrigeration system includes a chiller with an integrated free cooling system and refrigeration system. In certain embodiments, the chiller may be a single package unit with all equipment housed within the same support frame. The chiller may generally include three modes of operation: a first mode that employs free cooling, a second mode that employs free cooling and implements a refrigeration cycle, and a third mode that uses the free cooling system to remove heat from the refrigeration system. A heat exchanger may be shared between the free cooling system and the refrigeration system to transfer heat from the refrigeration system to the free cooling system.

Abstract: A refrigerant flow through a refrigerant circuit may be cooled with a cold cooling fluid flow from a thermal storage unit to generate a warm cooling fluid flow. The cold cooling fluid flow and the warm cooling fluid flow may be thermally isolated in the thermal storage unit, and a chiller system may cool the warm cooling fluid flow from the thermal storage unit to at least partially produce the cold cooling fluid flow.

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.

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.
