Abstract: A multiple circuit plate heat exchanger exchanges heat between a heat transfer fluid and refrigerant. The first portion of the heat transfer fluid flow enters a first refrigerant circuit and exchanges heat with refrigerant in the first circuit. The second portion of the heat transfer fluid flow then enters a second refrigerant circuit and exchanges heat with refrigerant in the second circuit. By employing a single heat transfer fluid pass, the average leaving temperature difference from each circuit can be reduced, reducing entropy generation and making the system more thermodynamically efficient.

A temperature sensor is positioned in association with the mold and provides an output signal. An auger is positioned partly within the at least one mold cavity. A mechanical drive rotatably drives the auger. A controller is coupled with the sensor and the drive, and controls operation of the drive depending upon the output signal from the sensor.

Abstract: A cooler is disclosed that utilizes beverage compartments that are integral to the container holding the refrigerant.

Abstract: A compact portable, self-contained and self-cleaning, domestic frozen food and beverage system capable of rapidly and automatically preparing and dispensing soft ice cream products, slush drinks, and frozen beverages in an efficient and spill-free manner. Ingredients are transferred into the freezing chamber via a paired bottle cap and receptacle that block ingredient transfer unless the bottle cap is securely seated within the receptacle. To begin the freezing process, a user would simply select and depress the start button corresponding to the type of product desired. An inlet port or ports allowing for pressurized fluid flow evenly about the freezing chamber and a rotating auger member disposed within the freezing chamber help the present invention to achieve a rapidly frozen product. Once operation begins, a microprocessor controls the temperature and speed of ingredient mixing with automatic shut-down occurring when auger torque indicates that the product has reached the desired consistency.

Abstract: A refrigerant gas leak is detected using remote maintenance technology, for chiller units installed in a substantially constant temperature industrial setting, where the influence of environmental temperature is largely constant and therefore can be accounted for in a predictable way. A simple and low cost method of detecting or predicting a refrigerant gas leak is proposed, on the basis of a relationship between evaporation temperature and at least one of atmospheric temperature, condenser cooling water temperature or refrigerant condensing temperature. Thus, a refrigerant gas leak can be detected on the basis of the evaporation temperature taking into account the effect of atmospheric temperature.

Abstract: Disclosed is an air-conditioning system for a motor vehicle with which individual zones of the interior can be individually air-conditioned. The air-conditioning system is divided by means of at least one dividing wall into sub-regions, with the dividing wall having a dividing wall opening which can be closed off. The heating or air-conditioning system improves the safety, for example, by reducing the amount of condensation on windows, while conserving installation space. In a first region (B1 or B2 or B3 or B4), the partial air stream flowing therethrough can flow through a sub-region (22HL or 22VL or 22VR or 22HR) of heater (22), and the partial air stream, which has already been heated in the first region (B1 or B2 or B3 or B4) can after passing through the dividing wall opening (82R, 82L), also flow through a sub-region (22FL or 22RL or 22RR or 22FR), located in the second region (B2 or B1 or B4 or B3) of the heater (22).

On the side surfaces 301a of the valve body 301 are formed protruding portions 301c, and to the protruding portions, penetrating holes 50 for inserting the bolt for mounting the expansion valve are formed.

Abstract: An ice machine configured in such a manner that all of its components, controls, and connections allow it to be secured to a wall at a location, conserving floor space while facilitating proper sanitation and ease of service. This is achieved by employing a bi-level design in order to increase efficiency of space use. The resulting configuration allows for decreased ice bin depth encroaching upon floor space adjacent to the wall at such a location. Alternate embodiments include bi-level remote condenser and remote condenser unit designs.
