Abstract: A refrigerant system is provided where the functions of an economizer heat exchanger and liquid-suction heat exchanger are combined. The two configurations are disclosed with a single common heat exchanger construction. In a first configuration, a series of valves selectively routes only one of two possible refrigerant flows through a common heat exchanger such that a control can selectively activate either an economizer heat exchanger circuit or a liquid-suction heat exchanger function. In a second configuration, both refrigerant flows are passed to the common heat exchanger through separate fluid lines and are selectively activated by the control. Variations of the second configuration are also disclosed.

Abstract: In an inlet heat exchange unit, wherein a refrigerant's dryness is low and its flow distribution is likely to cause deviation, a number of heat exchange passages in an ascending flow path at an upstream side is less than the number of heat exchange passages in descending flow paths. Accordingly, refrigerant flowing in the ascending flow path increases, and a region in which the refrigerant lacks is reduced, thereby decreasing temperature variations. In an outlet heat exchange unit, wherein the refrigerant's dryness is high and its flow distribution is unlikely to cause deviation, the number of heat exchange passages a most downstream path is greater than the number of heat exchange passages in the immediately preceding path, thereby suppressing an increase in flow resistance in the most downstream path and keeping flow resistance in the outlet heat exchange unit low.

Abstract: A cooling system for audio equipment uses a temperature sensor and Peltier effect module in a feedback control loop. The cooling system reads the temperature sensor to obtain the temperature of an audio component of the equipment, and adjusts the drive for the Peltier effect module that cools the audio component, to prevent overheating of the component. The cooling system may include an autonomous power supply that generates electric power from the audio signal driving a loudspeaker of the audio system. In another embodiment, the cooling system cools an audio component installed in a vehicle, even when the vehicle is unattended. To prevent discharge of the vehicle's battery, the cooling system employs a battery supervisor for turning the cooling system off when the battery has discharged down to a predetermined state.

Abstract: A tank is provided which can store, while cooling, drinks or other liquids, such as milk, having a storage temperature close to 0.degree. C. or below. A cooling tank (1) can be mounted on a truck or the like for transportation, while storing and cooling milk. It is characterized in that brine (antifreeze solution) which has a freezing point below 0.degree. C. is cooled in a cooling unit (34) and allowed to pass, without stagnation, along fluid passages in flow guide members (14, 18) installed on the wall surface of the tank body (10). The cooling unit (34) preferably has an evaporator in a heat pump type refrigerator (30) for example, which uses a refrigerant for cooling the brine. Since the brine with a freezing point below 0.degree. C. is used, a large-sized water tank for cooling becomes unnecessary, and further since the brine will flow without stagnation, the liquid inside the tank body can be effectively cooled.

Abstract: This invention relates to an improvement in a process and apparatus for delivering ultra high purity liquid carbon dioxide to a point of use at pressures above ambient without pumping. In the process a high purity carbon dioxide feed is charged to a vessel and at least partially solidified. Once filled, the slush or solid is isochorically heated, i.e., heated at constant vessel volume whereby the solid phase carbon dioxide is converted to a liquid. Liquid, then, is withdrawn from the vessel at a desired pressure at a rate at which the solid phase carbon dioxide is converted to a liquid. The improvement resides in effecting partial solidification and recycle of carbon dioxide.

Abstract: A humidity control method is provided for a multi-stage cooling system having two or more refrigerant circuits. A hot gas re-heat circuit having a hot gas re-heat coil is connected to one of the refrigerant circuits and is placed in fluid communication with the output airflow from the evaporator of that refrigerant circuit to provide additional dehumidification to the air. Humidity control is only performed during cooling operations and ventilation operations. During a first stage cooling operation using only one refrigerant circuit and having a low cooling demand, the request for humidity control activates the hot gas re-heat circuit for dehumidification and activates a second refrigerant circuit to provide cooling capacity. During a second stage cooling operation using two or more refrigerant circuits and having a high cooling demand, the request for humidity control is suspended and is initiated only upon the completion of the second stage cooling demand.
