Patent number: 4167965Abstract: A heat transfer system for effecting heating and cooling at maximum system operating cost efficiency in both modes of operation. In a preferred embodiment, a solar collector is utilized to transfer radiant heat from the sun to a heat storage medium, such as water, which is circulated through a water coil of an indoor heat exchanger. A conventional heat pump has an indoor refrigerant coil supported in the same heat exchanger in thermal contact with the water coil. During heating or cooling, air is passed through the heat exchanger and the heat pump is used to supplement the circulating water when the water is insufficient for heating or cooling purposes.The heat exchanger is formed by interpositioning the water carrying coil and the refrigerant carrying coil in thermal contact with each other through the use of common coil fins for the separate fluid carrying conduits.Type: GrantFiled: July 22, 1977Date of Patent: September 18, 1979Assignee: Carrier CorporationInventor: Richard D.

Patent number: 4165007Abstract: A vehicle frame for supporting large removable containers. One or more container securing members are attached to the frame. Each securing member can move between an inoperative or resting position and an operative or securing position. In the inoperative position, the securing member does not interfere with the loading, transporting, or unloading of a removable container. In the operative position, the securing member can engage a cooperating member of the container to secure the container to the frame. Lock means are associated with each securing member to prevent the member from inadvertently moving from the operative position to the resting position.Type: GrantFiled: December 5, 1977Date of Patent: August 21, 1979Assignee: Carrier CorporationInventor: Douglas S.

-
Patent number: 4158295Abstract: A spray generator for an absorption refrigeration system that includes a heat exchanger comprised of a multiplicity of variably spaced heat exchange tubes. The tubes are spaced close together near the top of the heat exchanger and spaced more widely apart near the bottom of the heat exchanger. Dilute absorbent solution is sprayed down through the heat exchanger. The close nesting of the tubes in the top portion of the heat exchanger retards liquid flow and aids heating of the solution. The wide spacing of the tubes in the lower section of the heat exchanger facilitate vapor flow out of the heat exchanger and eliminates liquid "blow-off". The top tubes are covered by a baffle to prevent the liquid solution from splashing out of the heat exchanger off of these top tubes.Type: GrantFiled: January 6, 1978Date of Patent: June 19, 1979Assignee: Carrier CorporationInventor: Howard W. Sibley

Patent number: 4133438Abstract: Apparatus for transferring refuse involve a container having a closure and an ejector head. A loading station includes a movable loading carriage, a packer assembly having a reciprocable packer head, and a plurality of power actuators. By positioning a container upon the loading carriage, the container becomes aligned with the packer assembly. The power actuators are actuated from a main control panel to move the loading carriage toward and away from the packer assembly, open the closure, and reciprocate the packer head for inserting refuse into the container. Subsequently, the closure is closed and the loading carriage is backed away from the packer assembly. The container is then transported to the unloading station. The unloading station includes a movable unloading carriage for receiving the refuse carrying container, and a plurality of power actuators. By positioning the container upon the unloading carriage the container becomes aligned with the discharge zone.Type: GrantFiled: May 19, 1977Date of Patent: January 9, 1979Assignee: Carrier CorporationInventors: Harvey W.

Patent number: RE30252Abstract: A high lift energy reclaiming circuit for use in a vapor compression refrigeration system, the circuit being interposed in the system between the compressor discharge line and the condenser inlet line. Refrigerant vapors discharged from the compressor are exposed to, and condensed into, a strong absorbent solution to develop temperatures within the mixture that are in excess of the saturation temperature of the discharge vapors. The mixture is brought into a heat exchanger where the high temperature energy is recovered by a heat reclaiming substance, such as water or the like. The diluted absorbent in the mixture is then separated from unabsorbed refrigerant vapors and the dilute solution flash cooled by expanding the solution to the inlet pressure of the compressor.Type: GrantFiled: May 1, 1978Date of Patent: April 8, 1980Assignee: Carrier CorporationInventor: Louis H.
