Definitions

  • the present invention relates to equipment for supplying chilled fluid for an air conditioning installation according to the preamble of Claim 1.
  • Air conditioning installations are known in the relevant art and are commonly used for air conditioning in the winter.
  • Radiant panel air conditioning installations are increasingly popular and commonly consist of equipment for supplying chilled liquid, or a chiller unit, having a water chiller, a pump and a set of pipes for distributing the water or other chilled liquid to one or more panels which form the terminal units for heat exchange with the environment.
  • Radiant panels are typically spiral-shaped and can be embedded in the floor, in the walls or in the ceiling of the environment to be air-conditioned, so as to be completely invisible and allow the space normally occupied by conventional environmental terminals to be used more satisfactorily for interior design. Furthermore, the larger heat exchange surface produces greater comfort.
  • radiant panels can use water at a lower temperature (35°C) than that used in a conventional radiator (60-90°C), resulting in greater efficiency of the heat sources used that can be used, such as heat pumps and condensing boilers.
  • a temperature controller connected to one or more temperature and humidity sensors located in the environment to be air conditioned, and to control valves located in the fluid circuit.
  • the temperature controller is set to keep the temperature of the water circulating in the panels sufficiently high to prevent the formation of condensation in the environment to be air conditioned.
  • the aforesaid solution does not remove the excess humidity present in the environment to be air conditioned.
  • the latent heat exchange in other words the removal of water vapour from the air by condensation, should constitute 20-25% of the total exchanged power.
  • a radiant panel installation has been proposed which is combined with a dehumidifier intended to remove a certain quantity of humidity from the treated air so as to bring the air conditioned environment into the comfort conditions which are ideal not only in thermal terms but also in terms of moisture content.
  • a dehumidifier consists of a refrigerating circuit and a fan, both housed in a one-piece casing.
  • the fan draws air from the environment at a certain temperature and sends it to an evaporating unit where the air is cooled and gives up some of its humidity by condensation of the water vapour on the cold surface of the heat exchanger.
  • the cooled and dehumidified air then passes through a condensing unit which returns the air, slightly heated, to the environment.
  • a dehumidifier therefore reduces the humidity but also heats the air which is reintroduced into the environment.
  • the aforesaid solution reduces the problems of the heating of the air by the dehumidifier, but causes an unacceptable increase in the costs of fitting the air conditioning installation, especially in the case of installations for domestic use. It should also be noted that the power per unit of surface area which can be given up by the radiant panel to the environment is limited by the typical heat transfer coefficients of the walls in which the panels are fitted, and also by the furnishings located adjacent to these walls.
  • the object of the present invention is therefore to propose an equipment for supplying chilled fluid to an installation for air conditioning of an environment, this equipment having structural and functional characteristics such that they meet the aforesaid requirements while simultaneously overcoming the drawbacks encountered in the prior art.
  • this object is achieved by an installation for air conditioning of environments according to Claim 13.
  • the number 1 indicates the whole of equipment for supplying chilled fluid to an installation 100 for air conditioning one or more environments, for example the environment 2 shown in Figure 4.
  • Each environment 2 is delimited by a plurality of structural elements (not shown in the figures) having corresponding inner surfaces inwardly facing said environment 2.
  • the structural elements of the environment 2 comprise a floor, a ceiling and a plurality of lateral walls.
  • the equipment 1 comprises first supply means for supplying a chilled liquid, for example water, at a first temperature T 1 to a fluid circuit for radiant panels 7 housed within at least one of the structural elements of the environment 2 to exchange heat with said environment 2 through the corresponding inner surface.
  • a chilled liquid for example water
  • the radiant panels 7 which are known and are therefore not described more fully, are housed within the lateral walls of the environment 2.
  • the radiant panels 7 can be fitted in the ceiling or in the floor, or in both of these.
  • the first temperature T 1 is set at a value such that the temperature of these inner surfaces is held above the dew point T dr of the air present in the environment 2.
  • the equipment 1 comprises second supply means for supplying a chilled fluid, which may be liquid or gas, at a second temperature T 2 to a heat exchange element 9 positioned within the environment 2 and having a heat exchange surface 9a designed to exchange heat with the environment 2.
  • the second temperature T 2 is set to a value such that the heat exchange surface is held at a temperature below the dew point T de of the air treated by said heat exchange element 9. Consequently, the second means for supplying fluid at the temperature T 2 can be used to supply a heat exchange element 9 in such a way as to condense the water vapour present in the air treated by it, thus appropriately dehumidifying the environment 2.
  • the first temperature T 1 is selected taking into consideration the thermal resistance of the walls in which the radiant panels 7 are fitted.
  • the chilled liquid can be delivered to the radiant panels at a temperature T 1 of 18°C and to the heat exchange element 9 at a temperature T 2 of 7°C.
  • the first temperature T 1 can be lower than the dew point T dr of the air present in the environment 2, while the temperature of the inner surfaces of the walls is nevertheless kept above the dew point T dr of the air present in the environment 2. This is because it is necessary to take into consideration the thermal resistance C w of the walls in which the radiant panels 7 are housed.
  • the dew point T dr of the air present in the environment 2 is 20.8°C.
  • supplying fluid at a temperature T 1 of 18°C to the radiant panels 7 enables the temperature of the inner surfaces 5a to be kept above 20.8°C.
  • the second temperature T 2 has to be lower than the dew point T de of the outside air, regardless of the dew point T dr of the air present in the environment 2.
  • the second temperature T 2 has to be lower than the dew point T dr of the air in said environment 2.
  • the temperature T 1 of the liquid supplied to the fluid circuit for the radiant panels 7 is higher than the temperature T 2 of the fluid supplied to the heat exchange element 9 which acts as a dehumidifier.
  • the heat exchange element 9 is advantageously the heat exchange element, or in other words the direct expansion terminal, of a fan coil unit which is fitted in the wall or false ceiling of the environment 2 to supplement the system of radiant panels 7, and which is supplied by the equipment 1 with a liquid at the temperature T 2 , for example 7°C.
  • the heat exchange element 9 can be the heat exchange element of a condenser unit in which the direct expansion terminal is fitted in the environment 2 and is supplied by the equipment 1 with a gas at the temperature T 2 .
  • the temperature T 2 of the gas of the condenser unit can be kept slightly lower than the temperature T 2 selected for the fluid supply of a fan coil unit.
  • the gas can be supplied at a temperature T 2 of 5°C.
  • the first supply means comprise a first chiller module 6 for supplying the chilled liquid at the first temperature T 1 to the radiant panels 7, and the second supply means comprise a second chiller module 8 for supplying the chilled fluid at the second temperature T 2 to the heat exchange element 9.
  • the two chiller modules 6, 8 of the equipment 1 can be two independent chiller units for supplying the radiant panels and the heat exchange element, of a fan coil unit for example, each chiller unit being thermodynamically optimized to supply liquid at the temperatures T 1 and T 2 respectively.
  • the equipment 1 comprises a casing 10 housing the two chiller modules 6, 8, a first delivery connection 11 for supplying the chilled liquid at the first temperature T 1 to the radiant panels and a first return connection 12 for receiving the liquid from the radiant panels, a second delivery connection 13 for supplying the chilled fluid at the second temperature T 2 to the heat exchange element 9 and a second return connection 14 for receiving the fluid from the heat exchange element 9.
  • the equipment 1 takes the form of a single unit having a casing 10 housing the two chiller modules 6, 8, each of which can in turn be housed in a corresponding casing (not shown in the figures).
  • the ratio between the thermal output required to supply the radiant panels and that required for the heat exchange element is not constant, but varies according to the type of installation. Consequently, the embodiment described above is particularly advantageous in that it enables two independent chiller modules with different outputs to be housed in the same casing, with the provision of a single electrical power supply and, as indicated by the rest of the description, a single control logic.
  • the two chiller modules 6, 8 may have the same dimensions in plan view and may be provided with suitable fixing means so that chiller modules with different outputs can be combined according to the requirements of the user.
  • the output of the chiller module 8 supplying the heat exchange element 9 can vary if, as mentioned above, the heat exchange element 9 is intended to treat the recirculated air from the environment 2 or, at least partially, fresh air from the outside.
  • the output is greater in the second case because the fresh air from outside, which is used to provide an air change in the air conditioned environment 2, has worse levels of temperature and humidity than in the case where the exchange element 9 only has to treat internal recirculated air.
  • Each module can include a compressor 15, an evaporator 16, a condenser 17, a pump 18, a thermostatic valve 19, an expansion tank 20, a water filter 21, valves 22 for the replacement of the water filter 21, and all the other typical plumbing components of chilled fluid supply modules required to reduce the installation time by comparison with the case in which these components have to be fitted separately.
  • the chiller module 6 for the radiant panels 7 can also include a water storage tank 23.
  • the heat exchange element 9 can be supplied with liquid, as shown in the attached figures, or with chilled gas, for example in a direct expansion system. In the latter case, clearly, the evaporator 16 of the chiller module 8 is omitted.
  • the second supply means comprise a chiller module 8 for supplying chilled liquid at the second temperature T 2 to the heat exchange element 9 and the first supply means comprise a three-way valve 24 for mixing the chilled liquid supplied by the chiller module 8 at the second temperature T 2 with at least some of the return liquid from the radiant panels 7 in such a way that chilled liquid at the first temperature T 1 is supplied to the radiant panels 7.
  • This embodiment provides a considerable cost saving, since it requires only one chiller module, in this example the chiller module 8, capable of producing liquid at the temperature T 2 .
  • the three-way valve 24 can mix some of the return water from the radiant panels 7 at 23°C with some of the chilled water at 7°C supplied by the chiller module 8 to supply the heat exchange element 9, thus providing a mixture of water having the temperature of 18°C required for the supply to the radiant panels 7.
  • the equipment 1 can advantageously comprise processing means 25 for receiving signals, which in the example are electrical signals but can alternatively be optical signals, at radio frequency or similar, representing the value T r of the temperature of the environment 2 and the value T sp of a temperature set by the user.
  • signals which in the example are electrical signals but can alternatively be optical signals, at radio frequency or similar, representing the value T r of the temperature of the environment 2 and the value T sp of a temperature set by the user.
  • the processing means 25 can process the two values of temperature Tr and humidity D r of the environment 2, in order to determine the value of the dew point T dr of the environment 2 and process this value of the dew point T dr of the environment 2 and the temperature value set by the user T sp to determine a value of the first temperature T 1 of the supply to the radiant panels 7, above the dew point T dr , and a value of the second temperature T 2 of the supply to the heat exchange element 9, below the dew point T dr .
  • the values of temperature T r , T sp and humidity D r are detected by one or more sensor means 26 fitted within each environment 2.
  • the processing means 25 can also process the value of the temperature T e and humidity D e outside the environment 2 to determine the value of the dew point T de of the outside air and process this value of the dew point T de of the outside air and the value of the temperature set by the user T sp to determine a value of the second temperature T 2 of the supply to the heat exchange element 9, below the dew point T de of the outside air.
  • the values of temperature T e and humidity D e are detected by one or more sensor means 27 fitted outside the environments.
  • the processing means 25 can also process the values of the temperature of the fluid delivered by and returning to the supply means 6, 8 and the values of temperature in the delivery to the radiant panels 7, to determine the values of the temperatures T 1 and T 2 of the supplies of the supply means 6 and 8 respectively.
  • the temperature values of the fluid delivered by and returning to the supply means 6 and 8 are detected by sensor means 28, 29 and 30, 31 respectively, and the temperature values of the delivery to the two radiant panels 7 are detected by sensor means 32, 33.
  • the processing means 25 are, for example, a logical processing unit of a known type, which is therefore not described more fully.
  • the equipment 1 can also comprise actuating means (not shown in the figures) for actuating the first supply means 6 to supply chilled liquid at the first temperature T 1 determined by the processing means 25, and for actuating the second supply means 8 to supply chilled fluid at the second temperature T 2 determined by the processing means 25.
  • actuating means (not shown in the figures) for actuating the first supply means 6 to supply chilled liquid at the first temperature T 1 determined by the processing means 25, and for actuating the second supply means 8 to supply chilled fluid at the second temperature T 2 determined by the processing means 25.
  • the processing means 25 can receive signals representing the values T r , D r of the temperature and humidity of the environments 2 and the value T sp of the temperature set by the user, and can process these values T r , D r , T sp to determine a plurality of optimal temperature values for the supply to the radiant panels for each of the environments 2. The processing means 25 then process these optimal temperature values of the supply to the radiant panels, in order to determine the value of the temperature T 1 of the liquid to be supplied by the first supply means 6.
  • the actuating means actuate the first supply means 6 to make them supply chilled liquid at this first temperature T 1 determined by the processing means 25.
  • the first temperature T 1 is the lowest temperature of the plurality of optimal temperature values of the supply to the radiant panels, while in winter operation this temperature T 1 is the highest temperature of said plurality of optimal temperature values of the supply to the radiant panels.
  • the installation 100 comprises fluid circuits for radiant panels 7 housed within at least one of the structural elements to exchange heat with the corresponding environment 2 through the corresponding inner surfaces, and equipment, in this example the equipment 1, for supplying chilled fluid, having first supply means 6 for supplying a chilled liquid at a first temperature T 1 to the fluid circuits for radiant panels 7, the value of said first temperature T 1 being such that the temperature of the corresponding inner surfaces is kept above the dew point T dr of the air present in the corresponding environments 2.
