    Abstract: An air conditioning companion stabilizer system for improving the operating cooling efficiency of refrigeration cycle components in air conditioning systems integrates the refrigeration cycle components with two independent, closed loops whose operation is complementary of one another. A temperature stabilizing loop functions in ambient conditions that lower cooling efficiency and is operative to absorb heat from the refrigerant exiting the condenser, thereby lowering the temperature of the refrigerant before it arrives at the expansion valve. A secondary loop, or charging loop operating in ambient conditions that enable optimal cooling efficiency facilitates the operation of the temperature stabilizing loop by priming a rechargeable heat absorbing component.

  • Publication number: 20150040586
    Abstract: In a temperature control system using a controlled mix of high temperature pressurized gas and a cooled vapor/liquid flow of the same medium to cool a thermal load to a target temperature in a high energy environment, particular advantages are obtained in precision and efficiency by passing at least a substantial percentage of the cooled vapor/liquid flow through the thermal load directly, and thereafter mixing the output with a portion of the pressurized gas flow. This “post load mixing” approach increases the thermal transfer coefficient, improves control and facilities target temperature change. Ad added mixing between the cooled expanded flow and a lesser flow of pressurized gas also is used prior to the input to the thermal load. A further feature, termed a remote “Line Box”, enables transport of the separate flows of the two phase medium through a substantial spacing from pressurizing and condensing units without undesired liquefaction in the transport lines.

  • Publication number: 20150033775
    Abstract: An apparatus and method for monitoring and controlling load requirements relating to a transport refrigeration unit, including receiving one or more power information from a load: a power consumption information or a power requirement information; receiving one or more state information from the load: state of a compressor, state of a condenser, state of a compressor fan, state of an evaporation fan or state of a condenser fan; determining the following based on one or more power information and one or more state information: a) an amount of power to supply, b) a time duration for supplying power, and c) an operational frequency. In one example, one or more auxiliary information are also used for the determination: a fluid leakage measurement, a current measurement, a timer measurement, a counter measurement, a controlled environment temperature, or an environmental temperature.

  • Publication number: 20150027139
    Abstract: A system including a setpoint module, a summer, a control module, and an expansion valve module. The setpoint module is configured to indirectly control sub-cooling of a condenser by adjusting a superheat setpoint based on (i) a return air temperature setpoint or a supply air temperature setpoint, and (ii) an outdoor ambient temperature. The summer is configured to determine an error between the superheat setpoint and a superheat level of a compressor. The control module is configured to generate a control signal based on the error. The expansion valve module is configured to electronically control a state of an expansion valve based on the control signal.

  • Patent number: 8935929
    Abstract: An HVAC evaporator unit and emergency drain pan are suspended from an existing overhead structure. Plural lateral beams are disposed along a horizontal plane, which support a pair of support beams, which support the HVAC evaporator unit. The beams are connected to each other by plural pivot connectors, which thereby defines a grid arrangement that is foldable about the plural pivot connectors. Plural pan support beams are suspended by pairs of pan hangers, which are connected to the ends the plural lateral beams. Plural flexible hangers are connected to ends of the plural lateral beams, for connection to and suspension from the existing overhead support structure. Hanger clamps are used to adjust the plural flexible hangers to facilitate height adjustment and leveling.

  • Publication number: 20150000310
    Abstract: An air conditioner is provided. The air conditioner includes at least one outdoor unit, a plurality of indoor units, and at least one remote controller to receive operation commands for the plural indoor units. One of the plural indoor units may be selected as a power-supplying indoor unit to supply electric power to the at least one remote controller, based on voltage values of electric power to be supplied from the plural indoor units to the at least one remote controller. The selected indoor unit supplies electric power to the at least one controller. The air conditioner enables a supply of electric power with a sufficiently high voltage to a remote controller by supplying electric power to the remote controller by one indoor unit exhibiting a highest voltage value of electric power to be supplied to the remote controller, as compared to other indoor units.
