Title: Water-heating dehumidifier

Abstract

A water-heating dehumidifier includes a refrigerant loop including a compressor, at least one condenser, an expansion device and an evaporator including an evaporator fan. The condenser includes a water inlet and a water outlet for flowing water therethrough or proximate thereto, or is affixed to the tank or immersed into the tank to effect water heating without flowing water. The immersed condenser design includes a self-insulated capillary tube expansion device for simplicity and high efficiency. In a water heating mode air is drawn by the evaporator fan across the evaporator to produce cooled and dehumidified air and heat taken from the air is absorbed by the refrigerant at the evaporator and is pumped to the condenser, where water is heated. When the tank of water heater is full of hot water or a humidistat set point is reached, the water-heating dehumidifier can switch to run as a dehumidifier.

  • This patent describes a water heater control system for constantly controlling the heating and use of hot water from a water heater unit of the type having water heater means with a water heater control means therefor converting between on for heating water and off free of heating water. The control system comprises a water inlet means for feeding water to the water heater means to be heated, a water outlet means for feeding heated water from the water heater means, and a water distribution means operably connected to the water outlet means for distributing hot water to be used.more » The water heater control system further includes: water temperature sensor means at least operably connected to the water outlet means for sensing the temperature of the water ready to flow to the water distribution means; processor and control means operationally connected to the water temperature sensor means and the water heating control means for determining the start of a particular time period.« less
  • There is provided a heat pump installation for the heating of tap water and for room heating purposes, e.g., associated office spaces in large warehouses where a number of refrigerators are operating. The heat pump receives its input heat from the heat liberated by the refrigerators. In order to protect the refrigerators from the influence of the heat pump, and in order to accomplish a smooth operation of the heat pump, the installation according to this invention exhibits the features: that the evaporator device of the heat pump is arranged in the form of parallel-coupled evaporator units each of whichmore » is assigned an expansion valve controlled by the refrigerant pressure at the unit outlet; that a by-pass line containing a valve which opens when the outlet pressure reduces is arranged between the high-pressure side of the heat pump compressor and the refrigerant circuit of the heat pump, following the evaporator units; that another by-pass line with a valve controlled by the pressure or temperature at the inlet side of the compressor is arranged in parallel with the evaporator units of the heat pump; and that each evaporator unit of the heat pump is arranged in a heat-exchanging relationship with its particular first condensor unit in each condensor device of the refrigerators said condensor devices comprising in each case at least one additional condensor unit for the dissipation of the residual heat, for example to the outdoor air,a third by-pass line being arranged in parallel with the second condensor unit, and a control means being arranged to control the flow distribution between the condensor units as a function of the desired refrigerant pressure after the condensor device.« less
  • An integrated water heating and space heating and cooling appliance is described comprising: a housing having a lower water storage section, a middle burner section, and an upper internal air handling section in an internal portion, and having a side external air handling section extending from the internal portion to pass through a building wall; an insulated hot water storage tank in the lower section of the housing; a burner and burner heat exchanger in the middle section for heating a liquid heating medium; a liquid to air heat exchanger in the upper section; a heat transfer fluid circuit meansmore » for selectively directing heating medium from the burner heat exchanger in the middle section into heat exchange relationship with hot water in the hot water storage tank; an air conditioner evaporator in the upper section adjacent to and in face to face relationship with the liquid to air heat exchanger; a blower in the upper section for blowing space conditioning air past the liquid to air heat exchanger and the evaporator for heating the air by the heat exchanger or cooling the air by the evaporator; an air conditioner condenser in the side section; a compressor operatively connected by conduit means to the compressor and evaporator to form a refrigeration system; and a blower in the side section for blowing external air past the condenser.« less
  • A system for heating or cooling room air and heating hot water is described that includes a heat pump having heat exchangers connectable to heated and cooled liquid circulation loops, a tank for thermal energy storage, solar heat collectors, and means to provide supplemental heating of the liquid.
  • An auxiliary heating device for supplementing the performance of a standard hot water type home heating system with the heat produced by combusting a low cost, readyily available fuel is disclosed. The device comprises a cylindrical fire chamber substantially closed at both ends and an elongated annular water chamber closed at both ends surrounding at least a portion of the fire chamber in a noncoaxial relationship thereto. Means are provided for plumbing the water chamber into the main heating system, whereby cool water enters the water chamber and heated water is pumped by the main system's pump to radiators disposedmore » around the home. A combustion air passageway is provided for passing air to the combustion chamber. Means for varying the size of the passageway in response to the temperature of water in the water chamber are also provided so as to control the combustion rate of the fuel. Means for supplying fuel to the combustion chamber are further provided.« less
