Definitions

  • the present invention relates to a heat pump of the air-water or air-air type.
  • a heat pump of this type described in U.S. 4,138,859 includes a frame which supports an evaporator and a fan, the evaporator comprising a helical coil of generally vertical axis.
  • the evaporator is traversed by a heat transfer fluid to take calories from the ambient air displaced by the fan.
  • the coil is placed in the chassis and is protected by a covering provided with air intake holes or slots.
  • the solar radiation can strike directly at certain times various points of the coil and can therefore cause differential heating or local overheating risking altering the operation of the compressor, in particular at start-up; on the other hand, the fluctuations in force and orientation of the wind determine variations in the flow of air extracted by the fan and consequently an irregular charge of the evaporator.
  • the invention aims to remedy the drawbacks of air-water or air-air heat pumps known by providing them with air intake means which, while remaining simple in design and convenient to use, are rendered insensitive to the irregularity of climatic factors.
  • the air inlet means comprise blades arranged at intervals regular and leaving between them E- channels co ul air ement; and the blades offer a cross section comprising a wide outer branch and a profiled inner branch and are arranged mutually so as, on the one hand, to shield the channels from the impact of the wind and the evaporator from the impact of the solar radiation and , on the other hand, to allow a tangential and regular entry of air to the evaporator.
  • the evaporator coil receives tangentially a constant air flow and is no longer subject to local overheating.
  • Protection against wind and sun is obtained for example by juxtaposing the blades so that the outer branch of a blade partially hides the inner branch of the adjacent blade.
  • the profile of the blades can be S-shaped so that the outer branch of the S of a blade partially covers the inner branch of the S of the adjacent blade, which improves the tangential effect sought for the introduction of the air, while the inner branch offers its convexity to the air flow to regulate it.
  • Each blade can be produced in a single molded or extruded part or, as a variant, in two separate vertical parts, one of which comprises the outer branch and the other the inner branch.
  • the outer and inner blade parts then form two separate concentric assemblies.
  • the slats can be grouped into several vertical louvers.
  • At least one of the louvers is rigid and can pivot around hinges or vertical axes integral with the chassis of the evaporator in order to take either the closed position for normal operation, or an open position providing a limited passage between two adjacent shutters.
  • the heat pump when the heat pump is of the monobloc type with cylindrical casing of vertical axis and therefore contains, in addition to the evaporator, the compressor and its regulating block as well as the condenser, it is provided for at least one louvers a fully open position allowing easy access to the interior of the cabinet to repair or replace the control unit or the compressor.
  • the evaporator according to the invention is integrated into a one-piece compression heat pump with the advantages which will be highlighted below, but it could of course be constructed separately as external element of an air-water or air-air heat pump whose compressor, condenser and regulation would therefore be grouped inside the building to be heated (so-called "split system” version).
  • the heat pump 10 has a base frame It houses the condenser and a cylindrical casing 12 constituted by a set of vertical blades 13, for example made of extruded aluminum, distributed regularly over the periphery of an evaporator 14 formed by a helical coil of which the general vertical axis is substantially the same as that of the covering.
  • a heat transfer liquid circulated in the coil is brought to a boil by drawing heat from the air which a fan 15 forces to pass through the channels 16 between the blades 13 and to lick the coil before expelling it by a opening not shown.
  • the rectilinear and vertical blades 13 protect the coil 14 from wind and solar radiation in all directions and they also allow a tangential introduction of air to the coil 14 (arrow 25 in Figure 5).
  • the blades 13 are grouped into three curved louvers 13a, 13b, 13c tightly enveloping the coil and pivotally mounted on hinges or vertical axes 17a, 17b, 17c.
  • the slats of each louver are fixed at their ends to a respective lower hoop and upper hoop mounted pi voters on the corresponding vertical axis.
  • the shutters can occupy a closed position for normal operation (Figure 2), a semi-open position (Figure 3) and, for at least one of them, a fully open position (Figure 4).
  • the louver leaves an opening 18 open between itself and the adjacent louver to provide a path to the air even if the channels 16 are obstructed by frost or snow.
  • the louver 13a allows intervention by the opening 19 on the compartment 20 containing the compressor 21, the regulation block 22, Vietnamese for example the disassembly and removal of these components according to arrow F.
  • FIG. 5 shows the shape and arrangement of the profiled blades 13 for protecting one of the louvers 13b.
  • the profile of the blades 13 is substantially in the form of a flattened S such that the outer branch 23 of each S covers the inner branch 24 of the S of the adjacent blade; the air flow thus takes place in the channels 16 formed between the branch 23 of a blade and the branch 24 of the adjacent blade according to arrow 25 and it can be seen that the air flow reaches tangentially and regularly with the helical coil 14 after sliding on the convexity 26 of the branch 24, whatever the force and the direction of the wind.
  • the heat due to solar radiation is absorbed by the blades 13 and it is returned indirectly to the coil 14.
  • the width of each blade is approximately 10 cm.
  • each blade 13 can be pivotally mounted on vertical hinges while the rotation about the general axis of the covering 12 of a crown connected to the blades makes it possible to modify the orientation of the blades.
  • the blades 13 are each in two separate parts, one forming the branch 23 and the other forming the branch 24.
  • the inner and outer branches then constitute two concentric rings.
