  • Publication number: 20220307746
    Abstract: A method for managing and controlling a heat pump based on a compression/expansion thermodynamic cycle of an operating fluid including at least: first and second heat exchangers; an expansion valve; and a compressor. The compressor is able to suck and compress a wet operating fluid. A plurality of temperature sensors detects the delivery temperatures Tm of the compressor, an evaporation temperature SST in the first exchanger, and a condensation temperature SDT in the second exchanger. The temperature difference between the lubricating oil in the compressor and the operating fluid at the compressor delivery is kept equal to or greater than a safety threshold OIL_SH such that there is no condensation of the operating fluid in the lubricating oil.

  • Patent number: 8161986
    Abstract: Dish-washing machine comprising a chamber (2) for washing articles (3), an air inlet line and an air outlet line both communicating with the chamber, air circulating means for forcing an inlet airflow sucked from the atmosphere into the chamber (2) via said air inlet line and exhausting an outlet airflow saturated with moisture after passing over said articles (3) to the atmosphere via said air outlet line; heating means are provided for heating said outlet airflow before exhausting to the atmosphere in order to reduce the relative humidity of the discharged air.

  • Publication number: 20120061052
    Abstract: A hydronic system (2) includes a vessel (4) having an external surface (8) and an internal surface (9) that defines a hollow interior portion (12) configured and disposed to store a first fluid medium. A heat exchange member (34) includes a body member (36) housing a heat exchange element (38) configured to facilitate an exchange of heat between the first fluid medium and a second fluid medium. The heat exchange member (34) is directly hydraulically connected to the vessel.
