Definitions

  • the invention relates to irregular states in refrigeration circuits in which a working fluid acting as a refrigerant is circulated in a thermodynamic cycle, such as the Clausius-Rankine cycle.
  • thermodynamic cycle such as the Clausius-Rankine cycle.
  • These are mainly heat pumps, air conditioning systems and refrigerators, as they are common in residential buildings.
  • Residential buildings are private houses, apartment building complexes, hospitals, hotel complexes, gastronomy and combined residential and commercial buildings in which people live and work permanently, in contrast to mobile devices such as car air conditioning systems or transport boxes, or industrial systems or medical devices. What these cycle processes have in common is that they generate useful heat or cold using energy and form heat transfer systems.
  • thermodynamic cycle processes used have been known for a long time, as have the safety problems that can arise when using suitable working fluids. Aside from water, the most common working fluids of the time were flammable and toxic. In the last century they led to the development of safety refrigerants, which consisted of fluorinated hydrocarbons. However, it turned out that these safety refrigerants damage the ozone layer, lead to global warming, and that their safety-related harmlessness led to design carelessness. Up to 70% of the turnover was accounted for by the need to refill leaking systems and their leakage losses, which was accepted as long as this was felt to be economically justifiable in individual cases and promoted the need for replacement purchases.
  • Propane is also heavier than air, so it sinks to the ground in still air and collects there. If part of the propane collects in a low-flow zone of the closed room in which the malfunctioning unit is located, the local explosion limits can be reached much more quickly than would be expected from the quotient of the total volume of the room and the amount of propane that had escaped.
  • the WO 2015/032905 A1 seeks to solve this problem by a generator for electric power in the opening or locking this space is integrated and when it is actuated in a first step generates and provides the electrical energy with which the sensor is activated, and in the event of an alarm, the Locking then does not release, but causes the closed room to be ventilated, and only allows unlocking and opening in a second step.
  • 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.
  • a negative pressure is applied in the space between the double-walled capsule and leaks that could occur at the openings for cooling water and brine are sucked out. The suctioned working fluid can then 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, cannot penetrate into the encapsulated interior.
  • the DE 41 14 529 A1 describes a safety device for a refrigeration system filled with a hazardous medium, which consists of at least one complete refrigeration unit that includes a refrigerant circuit with an evaporator, compressor and condenser, and a drive motor.
  • the system is enclosed in a gas-tight manner, with the enclosure being designed according to the maximum pressure that is technically possible in the event of a fault, and the connections for the coolant, a coolant and electrical supply, monitoring and control lines are routed pressure-tight to the outside of the enclosure.
  • An expansion tank can be connected.
  • the DE 195 25 064 C1 describes a refrigeration machine 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 is provided, and the space is filled with a refrigerant-sorbing substance.
  • the amount of sorbing substance is dimensioned in such a way that the entire amount of refrigerant that may escape can be absorbed and kept away from the environment.
  • the space filled with the sorbing substance is open to the environment. For heavier-than-air refrigerants, the space is open at the bottom, for lighter-than-air ones, it is open at the top, so a conveying fan is not required.
  • the sorbent is introduced into the housing and completely encloses the refrigeration machine or the refrigerant-carrying equipment. Baffles are provided on its way out to prevent shunt flows and force escaping gas through the sorbent. A double-walled embodiment, in which the sorbent is arranged in the double jacket, is also possible.
  • a measuring device for refrigerant can be provided at the outlet of the space filled with the sorbing substance to the environment.
  • the DE 195 26 980 A1 describes a device and a method for cleaning the air of enclosed spaces containing gaseous contamination. After the contamination has been detected by a gas sensor, it controls a compressor, which directs the air through an absorber located in this room, whereby the contamination is absorbed. The cleaned air leaves the absorber in the closed room.
  • the DE 20 2016 10305 U1 relates to an explosion-proof heat pump for tempering heat transfer fluids that is operated with a flammable refrigerant. It has an enclosure that contains all the equipment of the refrigeration circuit, and inside which a fan is arranged, which is designed to be explosion-proof. As soon as a sensor detects a leak, the housing is sucked off by the fan and thus flushed, and the resulting dilution ensures that no explosive mixture can form. The extracted air is discharged through an air duct. However, since the housing is deliberately not designed to be sealed, so that heated air is kept inside the housing in exchange for cool air from the environment, such a breathing device is not suitable for installation indoors.
  • the object of the invention is therefore to provide a device and a method for safe and energy-saving flushing of a housing that is installed in a residential building, and inside which a left-handed thermodynamic Clausius-Rankine cycle in a closed, hermetically sealed working fluid circuit using a flammable working fluid which is heavier than air in the gaseous state under atmospheric conditions.
  • Configurations of the invention relate to the scavenging air inlet, which is made up of several components. These components are the inlet of the scavenging air from the outside, the forwarding of the scavenging air into the interior of the housing with equipment, and the entry of the scavenging air into the interior of the housing.
  • the entry of the scavenging air into the interior of the housing is arranged on the upper side of the housing and takes place by means of a dispersing nozzle. This ensures that there is a slow downward flow without streak formation over the housing cross-section and the formation of vortices is minimized.
  • the place where the scavenging air enters the interior of the housing is normally not the same as the place where the scavenging air enters the housing from the installation room, but takes place via a line with devices that can also provide air suction from the outside outside of the building.
  • one embodiment of the invention provides a large number of inlets, for example in the form of slots or via a perforated plate, the location of which is locally adapted to the conditions at the installation site, and which are combined in a collecting line which is also equipped with a non-return device and a throttle.
  • the multiplicity of inlets can also be placed at some distance from the housing.
  • the outlet of the scavenging air from the interior of the housing is normally not identical to the outlet of the scavenging air in the bottom of the housing, the lowest point in the housing, but takes place via a line with devices that can also run partially inside the housing.
  • the scavenging air outlet line can therefore be connected at any point in the housing wall, regardless of whether the conveying fan is inside or outside the housing and inside or outside the installation room or building is arranged.
  • a dispersing device should be installed at the outlet of the drain outside the building, and the drain from the housing should also be routed to a location outside the building where there are no depressions in the ground, such as basement gratings or the like.
  • the conveying fan can be arranged in the intake area or in the discharge area, in one case it generates a slight negative pressure, in the other case a slight overpressure in the housing.
  • Further configurations relate to the heat balance of the scavenging air. If flushing air is routed from a closed room to the outside of the building, the same amount of air must flow into the building from outside. If the temperatures inside and outside the building are different, the scavenging air will result in a flow of heat, whereby the room temperature at the installation site is irrelevant. In practice, this means that without appropriate further measures, an undesirable heat loss or heat input would take place, depending on the operating mode, depending on the temperature difference between the inside temperature and the outside temperature. For this reason, the scavenging air can be both cooled and heated using the facilities for operating the cycle process.
  • the scavenging air extracted from the bottom of the housing is routed to a switchable branch, the branches of which are routed to additional heat exchangers, which are located in the heat carrier supply lines to the two heat exchangers of the cycle process.
  • additional heat exchangers can be located inside or outside the housing.
  • the invention also includes the method according to claim 6, wherein a conveying fan draws in the scavenging air while the housing is under negative pressure sets, the withdrawn scavenging air is passed into at least one heat exchanger in which the scavenging air is either cooled or heated against a heat transfer fluid which is connected to the refrigeration circuit.
  • the purge air must be heated.
  • it is fed into a heat exchanger, which directs the heated heat transfer fluid to the outside area, where it gives off heat to the environment.
  • the scavenging air serves as an additional heat sink and helps with the desired cooling of the building.
  • the purge air must be cooled before it leaves the building. To do this, it is fed into a heat exchanger that returns heat transfer fluid from the outside area before it is fed into the evaporator heat exchanger of the cycle.
  • the scavenging air serves as an additional heat source and helps with the desired heating of the building.
  • heat transfer fluids ie air, water, brine, heat transfer oils or the like.
  • cycle process is not operated or executed as a heat pump that can be switched between cooling mode and heating mode, or if it is multi-stage, other flows of heat transfer fluids can also be used.
  • the scavenging air can advantageously be connected to a device for leak detection.
  • the scavenging air operation can normally be severely restricted or even stopped, while the amount of air is increased accordingly when a leak is detected.
  • the conveyor fan can be equipped with a backup battery in the event of a power failure, and a solar-powered connection that can also keep the backup battery charged at all times is advantageous. If the conveying fan is arranged outside of the building, an integrated design with a solar cell and a reserve battery is also useful.
  • the housing 6 is usually soundproofed and therefore airtight, it can be slightly negative pressure, for example 20 or 50 hPa , endure. Structurally, water reservoir and switching elements can be integrated.
  • the housing 6 has line connections for the heat source, the heat source connection 7 and the heat source flow 8, and the heating circuit with the heat sink flow 9 and the heat sink connection 10.
  • the refrigeration circuit shown here in simplified form can also contain several heat exchangers at different temperature levels, a graduated pressure reduction, switching devices for heating in winter and cooling in summer, as well as a large number of sensors, although the flushing devices are basically identical.
  • the evaporator 5 and condenser 3 are interchangeable in their mode of operation or switching devices (not shown) in the refrigeration circuit can produce this functionality according to the known prior art, so that the heating circuit becomes the refrigeration circuit of an air conditioning system and the heat source of the heating mode becomes a heat sink in air conditioning.
  • the scavenging air enters the housing 6 through the dispersing device 11 and is distributed over the entire surface of its upper side.
  • the scavenging air is sucked in from the inside of the building via an air inlet 12 with several air inlet slots and via an air line with throttling 13 which is equipped with a non-return safety device 14 .
  • throttling has the effect that there is always a corresponding negative pressure inside the housing, which is maintained even during an interruption in the flow of scavenging air due to the non-return safety device in order to prevent leakage-related working fluid from escaping into the building interior.
  • the scavenging air is drawn off at the lowest point 15 of the housing 6 by means of a trigger 16 .
  • the devices in the housing are arranged in such a way that no shells or sacks can form in which working fluid that has escaped due to leakage can collect could. Due to the slight, preferably turbulence-free downward flow of the scavenging air, heavier gaseous components are safely conveyed down to the vent 16 and drawn off.
  • the two three-way valves 17 and 20 which lead to the scavenging air heat exchangers 18 and 21 are located in the scavenging air line 19 behind the trigger 16, which is routed within the housing 6.
  • both the branches and the scavenging air line and the heat exchanger can be arranged outside of the housing 6 .
  • the scavenging air is directed into one of the scavenging air heat exchangers 18 or 21 depending on whether the heat pump system is in heating or cooling mode.
  • this is the scavenging air heat exchanger 21.
  • the scavenging air gives off heat to the heat source connection 7, which is colder than the warm scavenging air. If the house heat pump draws its heat from the outside air, the heat source connection would be around the outside temperature and the discharged purge air would have a temperature just above that before it is discharged to the outside area. The majority of the heat from the exhaust air would be recovered in this way, since it subsequently enters the cycle process.
  • this is the scavenging air heat exchanger 21.
  • the scavenging air absorbs heat from the heat sink connection 10, which is warmer than the scavenging air when the outside temperature is higher than the inside temperature of the building.
  • a scavenging air heat exchanger in the line of the heat sink feed 9 would also be conceivable, which would have the advantage of a higher temperature difference in cooling mode, but would have the disadvantage that a higher load would arise in the cycle process, so the energy recovery would be lower.
  • the specialist will select the most favorable integration here in each individual case, whereby a third scavenging air heat exchanger could of course also be used.
  • the scavenging air is then conveyed through the discharge line 22 via a non-return valve 23, which, like the non-return valve 14, ensures that the housing 6 is kept under pressure, by the scavenging air conveying fan 24 to the outside of the outer wall 25 of the building and distributed via a dispersing device 26. In the unlikely event of an accident in which overpressure could build up in the housing, this route also serves as an emergency lowering.
  • FIG. 2 shows the case where the conveying fan 24 is arranged at the location of the air intake 12 inside the building. This has the advantage that, in the event of a leak, no contaminated air-gas mixture is sucked in, and the ignitability is further reduced if there is a risk of explosion.
  • the housing 6 is thereby placed under slight overpressure.
  • the other facilities correspond to the representation of 1 .
  • FIG. 3 shows the case that the conveying fan 24, as in 1 shown, is placed in the drain line.
  • the air intake 12 is outside the building, which reduces energy losses. Nevertheless, when passing through the heat pump, a heat exchange takes place, which takes place in the same way as when the air is sucked in inside the building as in 1 described can be compensated.
  • the housing is operated at negative pressure.
