Definitions

  • the present invention regards combined equipment for the climate control of environments provided with a heating plant with radiating strips, according to the preamble of the respective main independent claim.
  • the present equipment is advantageously intended to be employed in industrial or commercial field to heat in particular large size buildings, both for a total heating and for heating partial areas of the building and for producing hot air or water for the purpose of also heating other environments.
  • Such equipment is provided with a plant with radiating strips to be arranged slightly below the ceiling of buildings to be heated, in a manner so as to irradiate heat via irradiation towards things and people below, preferably with heat radiation in the infrared range.
  • Such plants with radiating strips of known type conventionally comprise closed circuit radiating ducts, which are connected to a burner, in which a fuel mixture composed of air and gas is made to burn.
  • the aforesaid circuit of the plant is intercepted by a fan advantageously placed next to and upstream of the burner in a manner so as to subject the entire radiating circuit to a reduced pressure also susceptible of maintaining the plant in safe conditions.
  • the burnt gas flow produced by the burner is mixed in the closed circuit with a flow of combustion products previously introduced and in circulation, heating it so as to form a heating carrier fluid which is made to circulate in reduced pressure conditions by the action of the fan.
  • the burners employed in such plants are conventionally provided with a combustion chamber, in which the comburent mixture, formed by air and gas, burns at a combustion head, generating a fume carrier fluid that is made to circulate inside radiating tubes together with the previously produced circulation fumes.
  • the colder recirculation fumes are mixed with the hotter ones produced by the burner and together they are made to circulate by the fan, which maintains the entire circuit in reduced pressure conditions. Therefore, the fan circulates in the circuit a flow rate of carrier fluid in part formed by the new much hotter burnt gases produced by the burner and in part by the cooler burnt recirculation gases which have already in part exchanged their heat with the radiating tubes during the circulation thereof.
  • heating plants with radiating strips are known that are provided with heat recovery devices placed to intercept the fume discharge stack. Such devices transfer the heat recovered from the stack by means of a carrier fluid which transfers heat into the environment to be heated by means of a heat exchanger.
  • the main drawback lies in the fact that such equipment pieces of known type are not included among those listed as “supplied from renewable sources” since the supply of their burner up to now is only obtained from non-renewable energy sources, and in particular fuels deriving from oil are normally used, or more generally fossil hydrocarbons, such as methane gas, LPG or diesel.
  • a further drawback lies in the fact that such equipment pieces, even if attaining a greater efficiency with respect to the heating plants with radiating strips of conventional type, have not an efficiency sufficiently high to meet current standards in the industrial field of heating of environments.
  • the carrier fluid thus heated by means of the heat absorbed from the air of the outside environment is compressed by a compressor, which creates a pressure difference adapted to force the carrier fluid inside the closed circuit, in particular towards a condenser, normally placed inside the environment to be heated.
  • a condenser normally placed inside the environment to be heated.
  • the high temperature and pressure carrier fluid condenses and transfers, to the environment to be heated, the heat previously absorbed from the outside environment.
  • the closed circuit finally connects the condenser and the evaporator by means of a thermal expansion valve, adapted to bring the carrier fluid (by now cooled) back to the operating pressure in order to once again be able to absorb heat from the outside environment.
  • a first drawback lies in the fact that the overall energy efficiency is strongly limited by the temperature difference between the outside environment and the environment to be heated. Therefore, in the winter seasons, or generally in the colder periods of the year, the aforesaid temperature difference is such to have a significant negative effect on the total efficiency of the heat pump plant. More in detail, when the temperature of the outside environment is lowered below 7°C, the efficiency of the heat pump plant decreases drastically. In particular, if the temperature of the outside environment falls below 2°C, the evaporator risks freezing and/or icing. If the evaporator ices over, the entire heat pump heating plant stops operating until there is the complete unfreezing of the evaporator itself.
  • unfreezing devices for allowing the evaporator to continue to work even at low temperatures, such as electrical heating elements placed at the evaporator itself, which by being heated due to ohmic effect increase the temperature of the latter and allow the operation thereof.
  • the patent EP 0099022 describes a heating equipment of known type which comprises a containment body in which a heat pump is housed, provided with an evaporator traversed by an air flow suctioned from the outside environment by means of a fan.
  • a burner is housed that is provided with an expulsion duct adapted to expel the discharge fumes into the air flow which intercepts the evaporator.
  • the patent EP 0099022 does not disclose that the circuit of radiating tubes is at least partially extended outside the box-shaped body and is intended to be arranged in an environment to be heated in order to transfer heat to the environment by means of irradiation, and that a recirculation duct, which is housed in the containment box-shaped body, places an initial section and a final section of said circuit of radiating tubes in connection with each other, forming a closed ring with said circuit; and that the impeller is housed in said recirculation duct, and that the fume expulsion duct is connected to said recirculation duct, and that said recirculation duct is close to said heating duct to heat said first air flow directed towards the evaporator.
  • the main object of the present invention is that of overcoming the drawbacks of the above-described already known prior art, presenting equipment for the climate control of environments that is capable of improving the overall efficiency of the equipment pieces of known type and does not require an increase of thermal power to be installed beyond that required in order to thermally control the internal environment. Further object of the present invention is that of presenting equipment for the climate control of environments which allows reaching high efficiencies by means of the at least partial use of a renewable energy source.
  • Further object of the present invention is that of presenting equipment for the climate control of environments which allows continuous operation that is safe and entirely reliable.
  • reference number 100 overall indicates equipment for the climate control of environments in accordance with a preferred embodiment of the present invention.
  • This is intended to be mainly employed in the climate control of the environments by means of irradiation and/or convection in industrial, commercial and private field.

  • the heating plant with radiating strips also comprises a circuit 5 of radiating tubes, which conveys a first carrier fluid 6 and is connected to the burner 2 to receive therein the high temperature combustion products susceptible of heating the carrier fluid 6 itself.
  • the circuit 5 of radiating tubes is at least partially extended outside the containment box-shaped body 1, being intended to be arranged in the environment to be heated in order to transfer heat to the latter by means of irradiation.
  • the circuit 5 of radiating tubes is provided with an initial section 5' connected in fluid relation with the combustion chamber 3 of the burner 2 in order to receive the combustion products, and with a final section 5'' connected in fluid relation with the burner 2 in order to allow at least part of the first carrier fluid 6 to return to the burner 2 and circulate inside the circuit 5 of radiating tubes.
  • circuit 5 is extended for most of its extension (from the initial section 5' to the final section 5") outside of the containment box-shaped body 1.
  • the heating plant with radiating strips also comprises a recirculation duct 7 which is housed inside the containment box-shaped body 1 and is susceptible of placing the initial section 5' and the final section 5" of the circuit 5 of radiating tubes in connection with each other, forming a closed ring with the latter, in a manner such that at least one part of the first carrier fluid 6 which exits from the final section 5'' returns into the initial section 5' of the circuit 5 itself.
  • a recirculation duct 7 which is housed inside the containment box-shaped body 1 and is susceptible of placing the initial section 5' and the final section 5" of the circuit 5 of radiating tubes in connection with each other, forming a closed ring with the latter, in a manner such that at least one part of the first carrier fluid 6 which exits from the final section 5'' returns into the initial section 5' of the circuit 5 itself.

  • the fume expulsion duct 16 is positioned upstream of the burner 2 and downstream of the fan 8.
  • the recirculation duct 7 which internally conveys the first carrier fluid 6, which is at higher pressure than atmospheric pressure since it is increased by the action of the fan 8, allows conveying at least one part of the first carrier fluid 6 itself towards the fume expulsion duct 16.
  • the mass of first carrier fluid 6 that is expelled through the fume expulsion duct 16 is equivalent to the mass of fuel mixture C that is forced into the burner 2.
  • the equipment 100 for the climate control of environments also comprises a heat pump heating plant.
  • Such heat pump heating plant is provided with a second closed circuit 9 in which a second carrier fluid 10 circulates and with an evaporator 11, which is housed inside the containment body 1 and is hydraulically connected to the second closed circuit 9 to heat the second carrier fluid 10.

  • the equipment 100 object of the invention, thus prevents the evaporator 11 from being externally iced, compromising the correct and effective operation of the heat pump heating plant, and simultaneously avoids the use of high energy-intensive unfreezing devices, such as electrical heating elements placed at the evaporator 11 itself, or reversals of the operating cycle of the heat pump plant.
