Definitions
- the invention relates to a device for generating cold water for the room cooling according to the preamble of claim 1.
- a such device is already from document DE-A-3 228 124 known.
- the object of the invention is to provide the cooling capacity of a device at the outset mentioned type to improve with little installation and cost.
- the task is characterized by the characteristics of the characteristic part of the Claim 1 solved.
- the evaporative cooler be on Plate heat exchanger is made of polypropylene.
- a further increase in cooling capacity is provided by the water condenser upstream air condenser reached in the exhaust air duct is arranged.
- Another advantage is the increase in the exhaust air temperature and the result resulting reduction in relative humidity. This eliminates the danger the formation of condensate in the exhaust air duct is reduced. By evaporating the in of the exhaust air after the evaporative cooler are the aerosols any bacteria in it, especially Legionella pneumophila, the Livelihood deprived. It is particularly advantageous here that the Air condenser is arranged in the exhaust air duct of the evaporative cooler.
- Another advantage is the compactness of the system. This will Energy losses from heating the cold water pipes between the individual components of the system and the usual energy consumption avoided for the pumps.
- the device or system has a refrigerator, with a Refrigerant circuit 1, in which a compressor (compressor) 2 is arranged.
- a condenser (condenser) 3 arranged, which is cooled by the second liquid circuit 4, the is described in more detail below.
- the refrigerant comes from the condenser 3 via an expansion valve 5 to an evaporator 6, on which a third circuit 7 is connected.
- the cooling power delivered by the evaporator 6 to the third circuit 7 becomes fed to a buffer 9 via a pump 8.
- a buffer 9 is the cooling capacity of a fourth circuit 10 Cooling surface 11 supplied via a distribution system 12.
- the capacitor 3 connected second circuit 4 is by a pump 13 through a Evaporative cooler 14 performed as a plate heat exchanger and is resistant to contamination and corrosion.
- the Air flows through the plate heat exchanger 14 and flows through an inlet 15 arrives between the plates and into the environment via an outlet 16 is delivered. This flow is caused by a fan 17.
- Water is introduced into the air flow via a distribution system 18 in particular sprayed, causing the cooling capacity of the air reached in the heat exchanger is increased due to the evaporative cold.
- a pump 19 for the introduction of the water there is a pump 19 in the water supply line.
- the Buffer 9 can be dispensed with.
- the liquid circuit 7 then leads directly to the distribution system 12.
- an expansion valve 5 can be a Heat exchanger 25 is used, which is flowed through by the water, which is then fed to the distribution system 18. This will make another one Enables improvement in cooling performance.
- the liquid 21 to be cooled can either be via the heat exchanger 23 and then via the evaporator 6 of the refrigerator or through Switch valve 24 only circulate via the evaporator 6.
- All parts of the device or system that is, all parts of the Chiller, the evaporative cooler 14 and the control and regulation and all liquids and live lines are within one Housing 20 arranged in a compact manner.
- the housing can consist of several easy to transport units.
