  • Publication number: 20230184457
    Abstract: A condensate, precipitation and recycled water recovery system is described, for use in cooling applications such as air-cooled air conditioning and refrigeration systems. The recovered and recycled water system is a method designed to assist the air-cooled condenser in cooling the refrigerant, prior to the refrigerant cooling control system evaporator. The system can include an electronic control system, although not essential in all embodiments. In one embodiment, at least one condensate, precipitation, and recycled water recovery system is attached to the condenser of the refrigerant cooling control system. In another embodiment, multiple condensate, precipitation, and recycled water recovery systems are located on the condenser of the refrigerant cooling control system.

  • Publication number: 20190093378
    Abstract: A heating system is described that uses solar thermal technology in the heating cycle using the compression principle to reduce the electrical consumption of the compressors, thereby increasing the efficiency of systems being used for heating with an increased refrigerant flow. Thermal energy provided from solar thermal energy collectors may be used. The rate of efficiency of the total heating system depends heavily on the size and construction of the heat exchanger array and the pipework to and from these heat exchangers. The system uses proper dimensioning, components in the pipework, and logic groups with sensors and actuators attached in that pipework to increase energy efficiency.

  • Publication number: 20180112651
    Abstract: A temperature control system includes: a compressor, a condenser, an expansion valve, and an evaporator all connected in series to form a refrigerant circuit. The system includes an electricity generating arrangement fluidly connected to the refrigerant circuit between the compressor and one of the condenser and the evaporator, the electricity generating arrangement comprising a solar thermal collector adapted to heat refrigerant leaving the compressor, and a fluid driven electricity generator adapted to receive refrigerant heated by the solar thermal collector.

  • Publication number: 20060096355
    Abstract: An apparatus and method for monitoring pressure within an adhesion promotion unit is provided. The apparatus in one embodiment includes a chamber configured to receive and heat a semiconductor wafer. A vacuum device is in fluid communication with a processing space within the chamber, wherein the vacuum device is configured to create a vacuum within the processing space. A vacuum monitor is also in fluid communication with the processing space, wherein the vacuum monitor generates a first electrical signal if gas pressure within the processing space is below a predetermined value. The apparatus may further include a processor in data communication with the vacuum monitor and the vacuum device. The vacuum device may generate a second electrical signal, and the processor generates a third electrical signal if the vacuum monitor fails to generate the first electrical signal within a predetermined amount of time after the vacuum device generates the second signal.
