Definitions
- the invention relates to irregular conditions in refrigeration circuits, in which a working fluid acting as a refrigerant is conducted in a thermodynamic cycle, such as the Rankine cycle.
- thermodynamic cycle such as the Rankine cycle.
- These are mainly heat pumps, air conditioners and refrigerators, as they are used in residential buildings.
- Residential buildings are private homes, rental housing complexes, hospitals, hotel complexes, restaurants, combined residential and commercial buildings and businesses in which people permanently live or work, in contrast to mobile devices such as air conditioning systems or transport boxes, or industrial equipment or medical devices. What they all have in common is that they use energy to generate useful heat or useful cooling and form heat-transfer systems.
- thermodynamic cycles have long been known, as well as the safety problems that can arise when using suitable working fluids.
- the best known working fluids at the time are combustible and poisonous.
- safety refrigerants consisting of fluorinated hydrocarbons.
- these safety refrigerants damage the ozone layer, lead to global warming, and that their safety-related harmlessness led to constructive inattentiveness.
- Up to 70% of the turnover was accounted for by the refill demand of leaking equipment and its leakage losses, which was accepted as long as this was considered economically justifiable in individual cases and promoted the need for replacement procurement.
- the lower ignition limit of propane as working fluid is about 1.7% by volume in air, which corresponds to 38 g / m 3 in air.
- Propane is also heavier than air, so sinks in still air on the ground and accumulates there. So if a part of the propane in a flow-poor zone of the closed space in which the disturbed unit is collect, the local explosion limits can be achieved much faster than can be expected from the quotient of total volume of volume to leaked amount of propane.
- the WO 2015/032905 A1 seeks to solve this problem by an electric current generator in the opening or its interlocking this space is integrated and when actuated in a first step generates and provides the electrical energy with which the sensor is activated, and in the event of an alarm Lock then does not release, but causes a ventilation of the enclosed space, and only in a second step, an unlocking and opening allows.
- the DE-PS 553 295 describes an encapsulated compression refrigeration machine in which the refrigerant compressor 1, its drive motor 2, evaporator 3, condenser 4 and control valve 5 are enclosed in a double-walled capsule 6 and 7, respectively. In the space between the double-walled capsule, a negative pressure is created and leaks, which could occur at the openings for cooling water and brine, sucked. The aspirated working fluid can subsequently be recovered if necessary. It should be noted that there is no ambient air within the encapsulated space and due to the negative pressure in the double jacket also can not penetrate into the encapsulated interior.
- the DE 10 2011 116 863 A1 describes a method for securing a device for a thermodynamic cycle, which is operated with a process fluid containing or consisting of at least one environmentally hazardous, toxic and / or inflammatory substance.
- a process fluid particularly ammonia, propane or propene
- the adsorbent is regenerated after use.
- the adsorbent may be in the form of a bed, a shaped body, a paint, a Spray film or a coating to be equipped.
- the support structure of the molding may consist of microstructure, lamellar structure, tube bundle, pipe register and sheet metal and must be mechanically stable and strong surface enlarging.
- a circulation of the potentially contaminated air is usually continuous, but can also be initiated by a sensor that turns on the ventilation after reaching a threshold value or in the event of a detected accident.
- the adsorption can be carried out inside or outside a closed space.
- the DE 195 26 980 A1 describes an apparatus and method for cleaning closed space air having gaseous contamination. Once the contaminant is detected by a gas sensor, it controls a compressor which directs the air through an absorber in that space, thereby absorbing the contaminant. The cleaned air leaves the absorber in the closed room.
- the DE 195 25 064 C1 describes a refrigerator with a gas-tight housing, which accommodates all refrigerant-carrying components of the machine, a space connecting the interior of the gas-tight housing with an outlet space is provided, and the space is filled with a refrigerant sorbing substance.
- the amount of sorbent material is dimensioned so that the entire amount of any escaping refrigerant can be absorbed and kept away from the environment.
- the space filled with the sorbent material is open to the environment. For refrigerants that are heavier than air, the space is open at the bottom, for those that are lighter, it is open at the top, so that a delivery fan is not required.
- the sorbent is introduced into the housing and encloses the chiller and the refrigerant-carrying facilities completely. On its way out, baffles are provided to prevent short circuit currents and force escaping gas through the sorbent. Also a double-walled embodiment in which the sorbent is arranged in the double jacket, is possible. At the exit of the space filled with the sorbent substance to the environment, a measuring device for refrigerant can be provided.
- the EP 3 106 780 A1 describes a heat pump system housed in a binder lined airtight housing.
- an adsorption unit can be arranged with a forced ventilation, which cleans the air in the housing in the recirculation mode.
- This recirculation mode can be continuous or only in case of failure or at regular intervals.
- a pilot burner, a pilot flame, a catalytic burner or a heating wire can be arranged, which burns possibly residual combustible impurities.
- a fresh air supply in connection with the discharge of purified exhaust air.
- the object of the invention is therefore to provide an improved lining device which solves the problems presented better and no longer has the disadvantages.
- heat transfer fluids are here all gaseous or liquid media to understand, with which heat is transferred, such as air, water, brine, heat transfer oils or the like.
- the advantage here is that in the case of a leakage with release of the working fluid, a displacement of the inert gas from the adsorbent takes place with simultaneous adsorption of the working fluid.
- the displaced inert gas thereby inertizes the interior of the container and at the same time reduces the danger of explosion.
- the desorption of the displaced inert gas causes the adsorptive heating of the adsorbent during adsorption significantly lower, since no longer the entire heat of adsorption is free, but only the difference between the heat of adsorption of the working fluid and the heat of desorption of the inert gas. This also prevents already adsorbed working fluid is expelled by heat development again.
- propane is used as the working fluid, activated carbon as the adsorbent and carbon dioxide as the inert gas.
- the activated carbon can be in Known manner be doped such that optimal loading is done by propane, but a chemisorption is to avoid this, since then the same desorption of carbon dioxide fails.
- such a lining is preferably made by dimensionally stable mats or moldings containing the adsorbent and can be easily removed and removed after opening the housing. They are typically permeable to gas and liquid on the side facing the interior of the container by means of a holding grid, while the dimensional stability is ensured by a stable rear-side structure.
- these mats or moldings on the inside facing the housing have a flat surface and on its upper side pull-down foil-like blinds that are pulled in the event of disassembly as a bag over the surface and then for the Disassembly and removal must be kept closed.
- this device is also used for assembly in order to prevent the inert gas from prematurely diffusing out of the lining.
- Fig. 1 shows a schematic diagram of a refrigerant circuit 1 with a compressor 2, a condenser 3, a pressure reduction 4 and an evaporator 5 in a closed housing 6.
- the housing 6 has a heat source connection 7, a heat source flow 8, a heat sink flow. 9 and a heat sink connection 10.
- the refrigerant circuit 1 is operated in this example with the flammable working fluid propane, which is also known under the name R290. Propane is heavier than air, therefore, it tends to sink in case of leakage in the refrigeration circuit 1 in the housing 6 down. Due to temperature differences in the housing and corresponding convection, leakage-induced propane is also found in the rest of the housing interior. This housing 6 is therefore completely lined with the adsorptive lining 11.
- Fig. 2 shows an adsorptive molded body of the type in the housing may have several or should be, these moldings can also completely enclose the housing interior, especially on the bottom, since leaking due to leakage of propane in air drops. Incidentally, such shaped articles also contribute to the reduction of noise emissions.
- the exemplary adsorptive shaped body 12 has in its interior an activated carbon mat 13, which consists either of activated carbon fibers or of activated carbon pellets, which are fixed in a permeable matrix. Also honeycombs are possible. On the back there is a supporting structure with click fasteners 14, with which the adsorptive molded body 12 is fixed to the inside of the housing 6. On the opposite side is a permeable retaining grid 15th
- a shutter device 16 For assembly and disassembly of the adsorptive molded body on a shutter device 16, which consists of rollers on which can be pulled up and rolled up on the front and back before use films before use and pulled down after use and closed down.
- the slides on the front and back can be there also form a bag, which has a pull closure and gas-tightly seals the adsorptive shaped body before and after use.
