Definitions
- Low-mass cooling elements in the sense of present invention are coolable elements, for example slats of a cooling ceiling, by means of which thanks to its relatively low heat capacity, it quickly changes to changing Heat loads can be reacted to.
- a chilled ceiling made a notable contribution; is in general but additionally to provide a supply of outside air, giving a further contribution to air conditioning is.
- ventilation aspects of secondary importance Planning information about Chilled ceilings can be found, for example, at Uwe Franzke in of the magazine "Ki climate - Refrigeration - Heating", 1992, pages 9 to 12.
- the air conditioning system described in WO-A-92/10707 avoids this cooling room heat through a cooling ceiling made of concrete, in the pipe are arranged.
- the cooling elements, namely the ceiling, is used as a cold store used during the night and as a heat sink during the day works.
- Chilled ceilings are often installed in offices where several people with a variety of electrical and electronic devices work.
- the one given Heat is dissipated by so-called "silent cooling", whereby the heat by radiation (around 60%) and by Convection from the people and devices to the chilled ceiling is transported.
- the cooling operation only takes place during the times when the heat load occurs, i.e. during the Working hours.
- With the people present in the room also connected to a damp load. So on the chilled ceiling no condensation forms, it must Ceiling temperature above the dew point temperature of the Indoor air can be kept.
- the heat dissipation capacity of a chilled ceiling is small designed so that the required comfort conditions cannot be met, the question arises how to fix this problem.
- a lowering the coolant temperature is generally due to a The formation of condensation is not possible.
- a Increasing ventilation generally makes additional Investment necessary and also affects the Room comfort due to increased air movement. So it seems to be forced to reduce the heat load or to increase the active cooling surface. would have both considerable costs. It is therefore the job of Invention to find a way with less cost connected is.
- the solution arises from a special one Method, namely the method according to claim 1.
- the dependent ones Claims relate to additional features of the process, that are beneficial.
- the method according to the invention for air conditioning relates for example a building interior, especially one Office space, the ceiling of which is at least partially coolable Elements.
- a cooling device and a circulating coolant and discharged to the Environment According to the masonry of the building used as an additional heat sink; periodically during times when there are no jobs this heat sink will take place by means of the Chilled ceiling in the interior caused temperature drop regenerates. Leave with the inventive method yourself with a chilled ceiling that has an instantaneous heat load can not dissipate the necessary comfort conditions produce.
- the cooling system of the office space shown in Fig.1 with the Masonry 2 comprises a chilled ceiling 1, a cooling device 3 and a control and regulating device 4.
- the cold Coolant 12 is with the pump 13 in the flow 11 of the coolable elements 10 of the cooling ceiling (cooling fins) promoted.
- Via a collector not shown the heated coolant 14 back into the Cooling device 3.
- the one recorded in the building interior Heat is applied via a heat exchanger 3a (circulation pump 23) given the environment.
- the room air can enter a chamber 60 through openings 61 above the cooling fins 10 be sucked off, with an invisible fan in the Box 62 generates the necessary vacuum in chamber 60.
- the air passes through the air duct 63 and the vertical pipe 64 returned to the work area.
- the current the air is indicated by arrows 6, 6 '.
- Figures 2 and 3 show examples of curves which the dependence of the temperature T on the time t during one day - from midnight to midnight.
- Stripe 100 indicates the period during which the The work phase lasts (comfort phase).
- the curves are partly with extended, partly with dashed line.
- the stripped or dashed curve sections correspond to the intervals, during which the cooling device in or out of operation is: arrows 31 mean the start of cooling, the arrows 32 End of cooling.
- the temperature T is during the Night around 24 ° C. With the cooling is already before the start Work phase 100 started. Even after completing the Work phase 100 will continue for a while chilled. After adjusting the cooling takes place because of the im Masonry 2 and in the furnishings of the office stored heat the temperature T again.
- Curve 602 relates to the case that the Chilled ceiling can dissipate the current heat load.
- the Cooling only needs to be performed during comfort phase 100 will.
- the temporary temperature drops on Beginning 101 and end 102 of phase 100 occur since the heat load is not yet or no longer full is trained.
- FIG. 3 shows curve 600 for the small cooling ceiling of the Example, to which curve 601 of FIG. 2 is assigned, but now the inventive method for Commitment comes. Thanks to the night - i.e. during the Regeneration phase - performed cooling that works Masonry as a supplementary heat sink during the day.
- the nighttime cooling can be done intermittently, like it is shown in Figure 3. It can also be continuous be performed.
- comfort conditions Before the start of comfort phase 100, comfort conditions must be met to be restored: for a period of for example 3 hours before the start of phase 100 not cooled, so that the temperature T increases again.
- comfort conditions can also be a shorter duration should be provided if during this duration by means of an additional heater (radiator 8, Fig.1) Room temperature is raised.
- the use of a Auxiliary heating also allows a relatively deep one Minimum temperature of the masonry 2 - for example 18 ° C - to manufacture (this temperature as a over that Storage volume mean value is to be understood).
- the Temperature of the masonry 2 can therefore be the daily average for example, be around 20 ° C.
- the temperature of the coolant in the supply of the cooling ceiling is advantageously kept as low as possible, namely in the Near the dew point temperature. It is possible to do this Keeping the temperature below the dew point, especially when means are provided with which condensing condensation water collected and removed can be. As a rule during the regeneration phase no or a smaller moisture load than during the Comfort phase 100 is present, the coolant temperature can easily be set lower at night than during the day. It can be advantageous if the air is dehumidified.
- the cooling capacity of the Masonry (and / or furnishings) is given and can in the short term, i.e. during a day, not to be influenced.
