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 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 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: Air cooled chillers have auxiliary heat recovery systems that include a heat recovery heat exchanger for transferring heat from a compressed refrigerant to a process fluid. According to certain embodiments, the air cooled chillers also includes a compressor, a condenser, an expansion device, and a controller to govern operations of the expansion device, a fan in the condenser, and other components of the chiller system. The controller may receive signals from temperature and pressure sensors located throughout the chiller system in order to determine a heat recovery load of the heat recovery heat exchanger. The controller may govern operations of the condenser fan and the expansion device according to a low heat recovery mode, an intermediate heat recovery mode, or a full heat recovery mode. In full heat recovery mode, the controller operates the expansion device based on subcooling detected in the heat recovery heat exchanger.
