Andreas Bangheri has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10605501
    Abstract: An absorption heat pump having a generator, a heat source to heat the generator to drive coolant vapor out of solution, a condenser for cooling the coolant vapor and an expansion valve that expand the coolant fluid as well as an evaporator for at least partial evaporation of the expanded coolant fluid against a medium which is connected to at least one absorber which absorbs the expanded coolant fluid. A hot gas line which branches off from a line for coolant vapor upstream of the condenser and is fluid-connected to the evaporator such that it bypasses the condenser and the expansion valve, a defrosting valve being provided in the hot gas line, by means of which the flow of coolant vapor through the hot gas line can be controlled. The absorption heat pump is operated in a cyclic circulation process.

  • Patent number: 6332328
    Abstract: A process for operation of an absorption heat pump in which in a boiling apparatus a solution which contains a refrigerant is heated by a burner in order to expel the refrigerant as refrigerant vapor; the refrigerant vapor is condensed in a condenser by interaction with a heat transfer medium; the refrigerant from the condenser is supplied to a vaporizer and an absorber; the solution which has been depleted of refrigerant from the boiling apparatus is supplied to the absorber; the solution which is rich in refrigerant from the absorber is pumped to a high pressure level and is returned to the boiling apparatus; and the heat transfer medium which has been heated in the condenser is supplied to a consumer and the heat transfer medium which has been cooled by the consumer is returned to the condenser is improved by measuring the outside temperature and the temperature of the heat transfer medium and adjusting the output of the burner depending on the measured temperature values, and by controlling the amount of
