Definitions
- the cold production systems have been developed according to the application needs. There are basically three fundamental types: absorption, compression and thermoelectricity. Its basic principles are well known: the elimination of heat from one place, taking it to a higher temperature, requiring energy input. If it is thermal, it is the absorption systems; If it is mechanical, it is compression and if it is electric, it is the Thermoelectric or Peltier systems. There are other more direct ones that eliminate heat, taking it from a hotter place to a colder one, taking advantage of the mechanisms of heat and mass transmission, or taking advantage of the evaporation of a liquid or the sublimation of a solid.
- the heat of phase change is used, in particular that of liquid-vapor.
- the most commonly used substances such as cold-producing fluids or refrigerators are: anhydrous ammonia, CFCs and CHCF composed of methane and ethane with chlorine and fluorine atoms, whose consumption is being banned or reduced, due to environmental pollution problems, in particular , for the attack on the ozone layer of the atmosphere.
- the refrigerating machine used to produce heat or pump it from low to high temperatures, is also well known are the so-called "heat pumps", which are in full development.
- heat pipes which consist of closed enclosures, usually tubular, where there is a liquid and its vapor and sometimes a wick or muslin are also known, although it is not widely used.
- the liquid phase rises by capillarity. Placed vertically or with a certain inclination, they can be used as cold producers
- Peltier effect pellets for the cooling of camping fridges is widespread and it is well known, the heat of the hot face is dissipated through a heat exchanger, which is usually made of aluminum with fins, performed by forced circulation of air through a fan; the cold that occurs on the other side of the peltier is conducted through a metal, usually aluminum to a bucket that is also metallic and the same mat.
- a heat exchanger which is usually made of aluminum with fins, performed by forced circulation of air through a fan; the cold that occurs on the other side of the peltier is conducted through a metal, usually aluminum to a bucket that is also metallic and the same mat.
- aluminum fins are usually placed In the cold face and in some cases the dissipation is increased by helping with forced circulation.
- a static cooling has been performed for the ice sheet and another with forced air. It is also known the double jump or the coupling of two effect pads
- Peltier in sene to increase the temperature jump.
- Each tablet can give, with a good performance, a jump close to 30 ° C.
- containers of one to two kilos are incorporated, of a product that stores cold (accumulator), either to extend the preservation of food at low temperatures in power supply cuts, or for use in portable or camping fridges, either to keep the temperature constant for a longer time helping the refrigerating machine.
- the present invention consists in combining the advantages of cooling with Peltier effect, that of thermosiphon circuits with changes in the vapor liquid phase, producing the phase changes in the places and at the desired temperatures, taking advantage of gravity so that the liquid phase return to the hot zone to cool and heat accumulation with phase change at the desired temperature for stabilization of the system, which facilitates the regulation of temperatures and allows for an energy provision for a normal or abnormal stop due to lack of electrical supply or when control systems operate, etc.
- the enclosure to be cooled can be a compartment, or two, thermally insulated, where the air circulates by natural convection, (optionally it can be forced).
- the heat that enters each of the two enclosures and that which can be produced by stored products, door openings, etc., is eliminated by evaporation of a liquid, which can be water and its vapor is condensed in the upper area of the enclosure. closed, where the cold faces of Peltier tablets are installed.
- Thermosiphons (5) and (8) Peltier pads pump said heat to the hot faces, needing to consume electrical energy that is transformed into heat, which has to be removed by the hot faces through the two thermosyphons (3) and (6).
- thermosiphon phase change (3) has to be a few degrees per above the maximum ambient temperature, in the figure it has been considered that it may be 32 ° C.
- the heatsink may be finned or with other types of additional surfaces.
- thermosiphon (3) if the fluid is water, it will boil in the area near the hot faces of the pads and will condense on the finned surface, which will be cooled by air in natural convection (optionally forced).
- Peltier effect pads to be used and their number will depend on the characteristics of the domestic refrigerator, the desired power and the type and thickness of the insulator. Its feeding must be done with direct current, at the most suitable intensity for the desired temperature jump (increase between 30 to 40 ° C).
- the liquid introduced in each thermosiphon, apart from serving as a transport vehicle acts as a thermal accumulator.
- a domestic refrigerator with capacities has been chosen: in the cooling zone of 167.5 I, (temperatures between 0 and 6 ° C) and in the freezing zone of 105 I, (temperatures between -18 to -20 ° C), which can freeze 21 kg per day of a food containing 85% water. Average ambient temperature 23 ° C.
- the insulation would be expanded polyurethane with a density of 40 Kg / m3, thermal conductivity coefficient 0.023 w / m.K., Thickness of both enclosures 6 cm.
- the pressures of the four circuits can be obtained theoretically or experimentally, by the latter means, as follows:
- the equipment is brought to an environment whose temperature is the maximum design plus three degrees, (35 ° C) if that it is 32 ° C, wait a few hours until its temperature stabilizes and it is emptied with a rotary pump, it is connected with a water container at the temperature of the chamber and allowed to aspirate the desired amount and It is empty again, until the water boils.
- the temperature is lowered or it is passed to room temperature and once it is reached, the pressure that will be the filling of the circuit of future manufacturing series is measured.
- the power supply of the pads would be done with direct current at the appropriate voltage, so that the intensity is optimal in the nominal design conditions. It is advisable to obtain it experimentally in each prototype model. It is recommended that the power supply of the pads be divided into two independent electrical circuits. For example, if ten are used (eight for the first jump and two for the second), feed in series to five (4 + 1), if the optimal tension is 11.5 v per tablet, the voltage would be 57.5 v, for each One of the two circuits.
- thermostats could be, in both enclosures or in the thermosyphons that cool them. 8
