  • Patent number: 6655157
    Abstract: A wet package precooler is operated inside a flower cooler room and includes a closed cabinet with a slotted opening in the top into which the flower packages slide. A conveyor on which the packages ride is provided inside the cabinet, a motor/blower assembly provides cooling air flow. By incorporating vertical cooling air flow, the machine cools the packaged flowers as they slide through the slot. The machine directs the cooling air into the top of the package, down through the flowers, and exhausts the air through hand holes and vents in the water container part of the package.

  • Patent number: 6637221
    Abstract: A method of controlling the capacity of an absorption chiller by regulating the heat input to a generator in response to a selected one of two system variables. The first variable involves the measured chilled water temperature leaving the system evaporator and the second involves the calculated solution concentration that is being returned to the absorber. Data relating to each variable is sent to a selector where it is processed so that the data can be used to control the heat input to the generator. The temperature data is used to control the heat input during normal chiller operation, however, the selector changes over control to the concentrate related data when the solution concentration level approaches the solution crystallization limit.

  • Patent number: 6637220
    Abstract: A routine of controlling the dilution cycle of an absorption chiller to determine when to initiate a dilution cycle, continue the cycle and terminate the cycle. The concentration of solution leaving the chiller's low temperature generator is calculated and the crystallization temperature of the solution is then determined. The crystallization temperature is compared to the ambient temperature and the result is used to determine whether to institute a dilution cycle, continue the cycle or terminate the cycle.

  • Patent number: 6631617
    Abstract: A two stage hermetic compressor which uses carbon dioxide as the working fluid. A pair of modules individually housing compression mechanisms are located at opposite ends of a module housing an electric motor. The modules are secured to one another when the compressor is assembled. Suction pressure carbon dioxide gas is compressed in the first compression mechanism to an intermediate pressure which is introduced into an electric motor module compartment. The intermediate pressure gas enters the second compression mechanism module through a suction port. A conical baffle is affixed to the upper compression mechanism module to protect the suction port from direct suction of oil and to separate oil entrained in the gas therefrom. The intermediate refrigerant gas is compressed to a discharge pressure and is discharged into a compartment defined in the second compression mechanism module. The discharge pressure gas is then exhausted to the refrigeration system.

  • Patent number: 6619069
    Abstract: Flexible conveyor belt of the type which can be assembled to form an endless loop, a part of which forms a number of layers stacked one on another. The belt (3) is constructed from mutually articulatable links which each comprise at least two transverse rods (13) which, at each side edge of the belt, bear support members (12) projecting upwardly from the plane of the belt, which are intended to support a belt layer lying above. The links are interconnected so that they can be displaced relative to one another along at least one side edge of the belt. The support members (12) are connected to the ends of the transverse rods (13) in the belt (3) or constitute extensions of these rods and comprise a stirrup-shaped support portion which projects upwardly from the plane of the belt and interconnects the rods (13) in an associated link of the belt. The invention also relates to a climate chamber comprising a belt according to the above, and a method for treating products in such a climate chamber.

  • Patent number: 6619059
    Abstract: A method and apparatus for cooling an air conditioning system's condensing coils utilizing air filter pad made of glass fibers with self contained, perforated water capillary tubes allowing moisture to permeate the filter pad. The filter dads are connectable in series and provided with integral mounting strips for fixed or magnetic, internal or external attachment to the condensing unit. Special adaptive solenoids are also provided to allow for minimum flow of water over long periods of time. Dual sensors are provided connected to both the high and low side of the compressor for sensing compressor temperature status and switching the solenoid on and off, thereby preventing freezing. A unique method for applying chilled water to the capillary tubes by coiling the capillary tube around the suction line of the compressor is utilized.

  • Patent number: 6615610
    Abstract: A concentric tubing apparatus prevents heat gain in an air conditioning system. The heat gain results from heat generated in an engine compartment of a vehicle. To accomplish this, the tubing apparatus includes a first and second refrigerant tubes. The first refrigerant tube is in fluid communication with a receiver and an evaporator of the air conditioning system to accommodate the flow of the refrigerant from the receiver to the evaporator, and the second refrigerant tube is in fluid communication with the receiver and the evaporator to accommodate the flow of the refrigerant from the evaporator to the receiver. The second refrigerant tube is disposed concentrically about the first refrigerant tube such that the second refrigerant tube insulates the refrigerant flowing in the first refrigerant tube from the heat generated in the engine compartment. Thus, heat gain in the refrigerant flowing in the first refrigerant tube to the evaporator is prevented.

  • Patent number: 6606881
    Abstract: A filter system for an absorption chiller includes a replaceable filter element, a plateable member, and a sacrificial member. The filter receives a weak solution from the chiller's evaporator, receives a stronger solution from the chiller's absorber, and discharges a mixture of the solutions to the chiller's generator. Conveying the weak solution to the filter system avoids creating an accumulation of lithium bromide in the evaporator and helps dissolve or flush inhibitors from the filter element on a continuous basis. Combining the weak and stronger solutions in the filter system attempts to confine a corrosion or copper oxide plating process to an area of the chiller that can be readily serviced. The plateable member and the sacrificial member provide replaceable or consumable members used in the corrosion or plating process.

  • Patent number: 6606879
    Abstract: An accumulator for use in a heat pump system accommodates the flow of refrigerant in first and second directions as the system heats and cools, respectively. The accumulator includes a body and a cap. The body includes an inlet for receiving refrigerant from a compressor and an outlet for sending refrigerant to the compressor. A first port communicates with a front end heat exchanger for receiving refrigerant from this heat exchanger when heating and for sending refrigerant to this heat exchanger when cooling. A second port communicates with a passenger compartment heat exchanger for sending refrigerant to this heat exchanger when heating and for receiving refrigerant from this heat exchanger when cooling. A reversing valve, disposed in the cap, moves between a first position when heating and a second position when cooling such that the accumulator can accommodate the flow of refrigerant in the either direction.
