摘要:
An automotive air conditioning system is provided comprising a duct for introducing a flow of air into a vehicle cabin, a closed-loop refrigeration circuit including a condenser and an evaporator, a temperature sensor arrange in the duct for measuring the temperature of the evaporator, and a control unit for selectively commanding operation of the system in accordance with the measured temperature of the evaporator. In a preferred embodiment, the temperature sensor comprises an infrared (IR) temperature sensor that is remotely positioned downstream of the evaporator such that the sensor can measure the temperature of a downstream surface of the evaporator. The use of an infrared temperature sensor allows the temperature of substantially the entire downstream surface of the evaporator to be measured instead of a small finite area of the evaporator.

A ceiling-embeded cassette type air conditioner has a driving fan, a heat exchanger, a cabinet, and a deflector. An air is controlled to have desired temperature and humidity while passing the driving fan and the heat exchanger. The cabinet and the heat exchanger define a fluid channel guided to exhaust ports between the cabinet and the heat exchanger. The deflector extends straight and inclined to the heat exchanger, so as to enable the air to smoothly flow toward the exhaust ports without a secondary air-flow. By the fluid channel, the quantity of blown-air is increased with the same motor while the noise is reduced with the same quantity of blown-air. Consequently, the performance and the efficiency of the air conditioner are improved.

In the method and apparatus of this invention a wafer for manufacturing semiconductor devices is held by a vortex-type substrate holder against a moveable frame during processing. Motion of the wafer is controlled with movement of the frame. The frame is shaped to provide a sealed chamber through which gas that is used to create the vortices is also re-captured. With such sealed chamber a higher heat conducting but more expensive gas can be recycled and used for the vortex holder and cooling of the wafer. In another technique of this invention, damage of the wafer edges from impacts with position limiters is avoided by inserting a small physical off-set of the center of mass of the wafer relative to that of the frame used to rotate the wafer. This prevents sliding of the wafer within the holder. In another feature of the invention end effects during treatment of the wafer are avoided by providing an extension around the wafer. The extension assures that the treating gas stream provides the same treatment to the edge of the wafer as in its center.

A heat pump system includes an outdoor unit, an indoor unit, a compressor, and outdoor and indoor fans. An outdoor heat exchanger coil is connected to an indoor heat exchanger coil by liquid and vapor tubes. A control system limits the pressure in the vapor tubes during heating mode periods of heat pump operation by using a temperature sensor including a switch operatively connected in the indoor heat exchanger coil for sensing a temperature in the indoor heat exchanger coil. The switch operatively connects in series with a motor of the outdoor fan, such that when the temperature sensor senses a predetermined temperature in the indoor heat exchanger coil, it causes the switch to reduce a speed of the outdoor fan, thereby reducing the temperature in the vapor tubes and indoor heat exchanger coil.

A prepackaged food vending machine limited cooling apparatus and method for food vending machines of the type used for storing and dispensing prepackaged foods at normal room temperatures. The apparatus includes an elongated air conduit connected at one end thereof to, and in airflow communication with an interior of, the food vending machine. Another end of the air conduit connected to, and in airflow communication with a refrigerated interior of, a cold beverage vending machine. An airflow device, e.g. a blower or axial fan, is positioned in air flow communication between the interiors of the food and beverage vending machines whereby cold air within the beverage vending machine is transferred through the air conduit to the interior of the food vending machine in an airflow volume sufficient to reduce the air temperature within the food vending machine to a predetermined temperature below room temperature toward the operating temperature within the interior of the refrigerated beverage vending machine.

A refrigerated body generally in the form of a cuboid with insulated walls, floor and ceiling with a door in one of the walls. A refrigeration unit is provided for the body with a heat sink heat exchanger unit positioned in the body and a heat source heat exchanger unit exterior of the body. Preferably the heat sink is located below the ceiling in the body and comprises two heat exchanger units with a fan positioned therebetween. The fan blows air in a longitudinal direction and a guide plate arranged parallel to a side wall opposite the door directs air from one heat sink to a discharge location near the floor of the body with the remainder of the air being directed longitudinally through the body.
