Definitions

  • the present invention relates to a thermal insulating system and relative realization process for a refrigerating apparatus, comprising a compressor for compressing the refrigerant fluid, a condenser for condensing the refrigerant fluid coming from the compressor, means for expanding the refrigerant fluid coming from the condenser and for supplying it to at least one evaporator means, a return duct connecting the outlet of the evaporator means to the inlet of the compressor and at least one cooling compartment containing the evaporator means.
  • a refrigerating apparatus in particular a freezer, has substantially two distinct operating phases; a freezing phase (when fresh foods are introduced to be frozen), and a preservation phase (when the foods have been brought down to the required temperature at which they must remain).
  • a freezing phase when fresh foods are introduced to be frozen
  • a preservation phase when the foods have been brought down to the required temperature at which they must remain.
  • This loss is directly proportional to the temperature difference existing between the cooling compartment and the external environment, and inversely proportional to the therman resistance of the walls; for example in a freezer or in the freezing compartment of a combined or double-door refrigerator apparatus (which can reach -25 o C ) in the worst ambient conditions envusaged (32 0 C) there is a temperature jumpof 57°C, and even between the fresh food compartment of a refrigerator apparatus (which can reach temperatures of about Q°C) and the external environment in tropical climates (which can rewch 40-45 o C) there is a temperature difference of 40-45°C.
  • the object of the present invention is to overcome the above mentioned disadvantages and provide an insulating system for the walls of the refrigerating apparatus which will ensure a significant reduction of the losses of cold, and consequantly a significant saving of energy during operation, and which will also be reliable and will not alter its effectiveness over a long period of time.
  • a further object of the present invention is to indicate a process for the industrial realization of the said system which will be relativaly simple and economical so as to allow to be utilized for mass-production.
  • an insulating system for a refrigerating apparatus comprising a compressor for compressing the refrigerant fluid, a condenser for condensing the refrigerant fluid coming from the compressor, means for expanding the refrigerant fluid and for supplying it to at least one evaporator means, a return duct connecting the outlet of the evaporator means with the inlet of the compressor and at least one cooling compartment containing the evaporator means, characterized by the fact that at least one of the walls of the cooling compartmente is constituted by two plates of air-impermeable material (11, 16) maintained substantially parallel to one another and whose facing walls are specularly reflecting, and by a seal (14) which is also air-impermeable and which, together with the two plates (11, 16) forms a cavity in which a vacuum is formed to increase the thermal resistance of the wall and thus allow an improved conservation of cold within the cooling compartment itself.
  • a removable freezer compartment 20 which also includes two side walls 1' (Fig. 4) which form a hollow parallelepiped within the cavity of which there has been formed a vacuum 1/10 - 1/100 tor (the way this cavity is formed will be described in more detail in Fig. 3), an upper back wall 2, which forms part of the freezer compartment 20 itself, filled with molded high density insulating material, an upper evaporator plate 3 rigidly connected to the upper back wall 2, an upper door 4 thermally insulated in a known way.
  • a fresh food cooling compartment 21 comprising a lower door 5 also thermally insulated in a known way, a lower evaporator plate 6, a lower back wall 10 which allows the insertion of the lower evaporator plate 6 into the compartment 21 and is also filled with molded high density insulating material and upper, lower and back sidewalls 9for the compartment 21 which are filled with polyurethane foam.
  • a molded high density material has been used because it has a thermal resiatance approximately equal to that of a polyurethane foam, so as not to create in the walls of the refrigerator apparatus zones of discontinuity of insulation.
  • FIG. 2 which represents an axonometric projection of the same refrigerator apparatus as shown in F ig. 1, there are shown, for the sake of clarity, only some of the components shown in Fig. 1, which are indicated by the same reference numerals as in Fig. 1.
  • an outer plate 11 formed by a welded stainless steel sheet having a thickness of about 1,5 mm, whose outer face is painted and the inner face is chromium-plated to make it reflecting, an inner plate 16 positioned at a distance of about 15-20 mm from the outer plate 11, formed from a welded stainless steel sheet having a thickness of about 1,5 mm; whose outer face is painted and the inner face is chromium-plated to make it reflecting; the two plates 11 and 16 are shaped in such a way as to form a hollow parallelepiped; a hard closed cell rubber seal 14 having on the inner side two grooves 24 in which there is first spread silicone grease and into which the two and edges of the two plates 11 and 16 are then inserted, an evacuating tube 13 inserted into outer plate 11 and communicating with the cavity between the two plates 11 and 16 which serves to suck the air contained in the cavity and create the
  • the process for assembling the freezer cell 20 described in relation to Fig. 3 is clearly apparent also from a study of the Fig. 2.
  • the compartment is assembled separately and is then positioned in the refrigerator apparatus in such a way that it may eventuallybe easily removed and replaced by the technical service personnel.
  • a suction pump is connected to the evacuation tube 13 and the suction of air commences.
  • the use of the silicone grease which has been spread into the grooves 24 of the seal 14 is indispensable because if the grease were not there the air would enter the cavity through the empty spaces wing to the imperfect contact between the two plates 11 and 16 and the seal 14, and the air which would be drawn from the cavity would enter from said empty spaces, thus preventing the formation of the vacuum.
  • the suction is continued until a degree of vacuum of 1/10 1/100 tor has been reached, and at this point (with the suction pump still working) the evacuating tube 13 is throttled a,d hermetically closed.
  • the spacer grid 12 is indispensable because otherwise the two plates 11 and 16, because of the external pressure, could even flex into contact with one another annulling the effects of the insulation due to the vacuum.
  • This necessity carries with it the disadvantage that a certain quantity of cold is dispersed by conduction through the said spacer grid 12, so that to minimize these losses the meshes of the said grid are very wide, the material of which it is made is an excellent insulator, and moreover the profile which comes into contact with the two plates 11 and 16 is given a pointed shape such as to minimize ths said contact area.
  • Figures from 6 to 9 show.in more detail thz process of realization of the thermal insulating system according to the present invention.
  • an outer structure 30 made of plate (Fig. 6), in the form of a parallelepiped with the ends open, which forms the outer plate 11 shown in Fig. 3,and which is conveniently positioned in a respective mounting equipment comprising for example (Fig. 10) four centering rollers 50, fixed on a base 52, on which there is formed a housing for a seal 14, and bearing on each of the four outer sides of the structure 30.
  • an inner structure 31 made of plate also positionedby means of four centering rollers 51 inserted in its interior, on each side, and having the form of a parallelepiped with the ends open which forms the inner plate 16 shown in Fig. 3.
  • the spacer grid 12 which in Fig. 7 is shown as being composed of four portions 33 of equal shape, also formed by meshes crossed at right angles and also made of the same materials as already defined for the grid 12.
  • the teeth 25' which project from the portions 33 and which come into contact with the structures 30 and 31 are preferable defined by a profile forming an angle of 120°. In this way the area of contact between the grid 12 and the structures 30 and 31 is very much reduced, by about 90%, and consequently there is obtained a reduction of the quantity of cold dispersed because of the conduction through the said grid 12.
  • each portion 33 is rectangular (or square) when seen in plan,with a substantially rectangular plane end wall 36 whose perimeter is defined by a plane section 37 on a smaller side, a plane section 38 on a larger side from which a plurality of teeth 25' originate towarts the outside, the first of which in the direction towards the plane section 37defines abeveled section 40, opposed to the section 37, and a plane section 41 provided with the teeth 25', opposed to the section 38; towards the end situated near the section 37 section 41 forms a plane step 42 projecting towards the outside.
  • Sections 37 and 40 are then connected to the respective sections at the other end of the portions 33, 43 and 44 by means of plane walls 43 and 44,respectively.
  • the bearing of the plane surface walls 43 on the structure 30 does not deteriorate the thermal insulation between the structures 30 and 31, because the bearing of the portions 33 on the structure 31 takes place only by means of the teeth 25'.
  • the seal 14 is applied also to the upper end of the gap between the structures 30 and 31, with the important modalities already described hereinabove, i.e. with the use of the silicone grease spread into the grooves 24 of the seal 14.
  • the vacuum is then created within the gap, as already described hereinabove, and with the described configurationof the grid 12 provided with the pointed teeth 25' (Fig. 9) a deformation towards the interior of the gap of the structures 30 and 31 (of about 0,5 0,3 mm), so that the teeth 25' engage the inner surface of the structures 30 and 31.
  • This engagement ensures a stability of positioning of the grid 12 within the gap between the structures 30 and 31, thus allowing to maintain the relative and parallel position between the structures 30 and 31 and, consequently, a constant positioning of the sels 14 against the edges of the structures 30 and 31, which ensures the keeping of the degree of vacuum created within the gap itself.
  • the seal 14 abuts agains the plane end walls of the portions 33.
  • the inner walls can be chromium-plated or polished or painted by alluminizing or other similar technological processes.
  • the refrigerator apparatus Since the average life of a refrigerator should be":at least 10-15 years, and since it is possible that with the ageing of the materials air molecules will enter the cavity between the two plates 11 and 16 degrading the vacuum which has been formed in it, it may be envisaged to provide the refrigerator apparatus with an instrument for measuring the degree of vacuum and to provide the evacuating tube 13 with a valve accessible from the outside, in such a way that should the degree of vacuum become degraded to less than an optimum value it can be easily renewed, possible during a maintenance operation performed on the apparatus.
  • the freezer compartment 20constructed in one of the ways mentioned hereinabove is then mounted on the refrigerator apparatus; from the side having the fixing bracket 15 the are inserted into the apparatus the upper evaporator 3 and upper back wall 2, which are rigidly conneted to one another, until a perfect contact between the said upper back wall 2 and the seal 14 of the freezer compartment is obtained; from the opposite side the upper door 4 is introduced in such a way as to obtain a perfect contacto also between this latter and the seal 14 (by means of the coating wall 23).
  • the mounting of the upper back wall 2 and of the upper door 4 is carried out in such a way the freezer compartment 20 can be easily removed and replaced in the event of the vacuum contained therein being degraded to below a level which would no more ensure a good degree of insulation.
  • the number of insulating walls obtained by using the technique described can be increased to obtain an improvement in the insulation or can be reduced depending on the objective which it is intended to achieve;
  • the wall which separates the freezer compartment 20 of a combined or double door refrigerator from the fresh food compartment 21 can - be insulated by known methods or can even be insulated by rendering less efficient the usual insulation for the purpose of supplying cold from the freezer compartment 20 to the fresh food compartment 21.
