Double flash evaporation cooling system

Technical field

The utility model relates to double flash evaporation cooling system.

Background technology

Indirectly/direct evaporative cooler (IDEC) is double flash evaporation cooler, wherein, double flash evaporation cooler is a kind of system adopting " aobvious refrigeration technique ", and system can not increase humidity in the first phase and can not carry out evaporative cooling in second stage.

Showing cold is a kind of technique cooled air under the condition not changing steam absolute humidity and level.Therefore, any absolute humidity is there will not be to increase or reduction situation in this technical process.As conventional psychrometric chart, namely as shown in Fig. 1, the cooling procedure of primary air is shown as from A point to B point.Aobvious cold mainly through being realized by the secondary gas flow of C point to D point.Due to secondary gas flow can flow into treated surface formed thinner " moisture film " alternately add wet channel, therefore, it can be collected and be vaporized by moisture film and the moisture produced, thus causes temperature to raise.This process refers to C point in Fig. 1 to D point.

Owing to having three kinds of main advantageous characteristics, therefore, IDEC can replace the both vapor compression indoor air conditioning system under drying and appropriate dry climatic condition.

1. energy-conservation

IDEC unit does not adopt refrigeration compressor, therefore more energy-conservation than typical air conditioning systems.

2. higher cooling capacity

In addition, compared with traditional single stage (as directly) devaporizer, as a kind of double flash evaporation system, IDEC unit has higher cooling capacity.

3. low moisture

The moisture that IDEC unit discharges to air conditioned spaces is less, thus can provide better indoor environment and higher personnel's comfort level.

All above-mentioned three kinds of advantageous characteristics can assist to alleviate the environmental nuisance caused because of typical air conditioning systems.

Indirect evaporating-cooling is mainly by making two airflow passes by thinner and parallel heat exchanger plates and alternately dry and add that system that wet channel forms realizes.Be about to the airflow passes dry channel carrying out cooling; Meanwhile, secondary gas flow flows through and parallel adds wet channel.In this case, the thermograde existed between the last air in thinner and parallel heat exchanger plates two ends and auxiliary air will be ordered about heat and be flowed to auxiliary air end from primary air end.At this moment, can there is water mists on the surface and the moisture film formed occurs directly to contact with because adding green end heat exchanger plates in secondary gas flow.Moisture film then can carry out cooling heat transferring plate mode by absorbing required latent heat is vaporized.Therefore, due to heat can from the dry end of heater be delivered to realize cooling by evaporation add green end, air-flow is that mode by contacting with the desiccated surface of coldplate realizes cooling thus.Concerning the IDEC of standard designs, before cooling air-supply enters building, in the direct evaporating-cooling stage, the air-flow being in indirect evaporation stage downstream can be cooled further.

Two-stage and single-stage evaporation cooling field have employed multiple conventional art.

In a kind of technology, there is a definite limitation to the great-leap-forward air supply duct for fixing or install machinery.And, may be difficult to increase plate structure.

In another kind of technology, be hot briquetting and be made up of molding cabinet due to whole heat exchanger, therefore increasing size has a definite limitation.

In above-mentioned two kinds of technology, due to non-mounting filter and existence conditions is not aseptic, therefore there is a definite limitation to pure air.

There is following demand in IDEC system, namely must be scalable, energy-conservation, must sterilizable material be adopted, not need cleaning fluid (as air), the evaporative fluid (as disinfectant) of sterilization can be conveyed through and there is higher operational efficiency.

In DAMA 7 heat exchanger, cool primary air 23 by the secondary gas flow 26 flowing through alternate channel.Aobvious cold air 24 is called after the primary air 23 inputted flows out from DAMA 7 heat exchanger.Auxiliary air 26 be through the 1st stage and the 2nd stage cooling primary air 23 a part and be according to the rules line flows through the proper proportion part of the alternate channel of HE-I DAMA 7, as shown in Figure 2.Do not belonging in certain example of the present embodiment to restriction of the present utility model, flow through alternately add after wet channel cools primary air through first stage DAMA 7 and second stage heat exchanger 8, amounting to the auxiliary air accounting for primary air 40% will be supplemented by main stream primary air.

This auxiliary air 26 flows through the alternate channel of DAMA 7 and evaporates the moisture film formed by the supporting cylinder 19 of moisture.Therefore, the enthalpy of auxiliary air and absolute humidity all can increase.And the heat evaporated needed for this moisture film can be obtained by the primary air 23 flowing through DAMA 7 thin-walled.Therefore, aobvious cold treatment can be carried out by the mode of moisture film moisture in evaporation alternate channel to primary air 23.Then, as secondary exhaust mouth 27, auxiliary air 26 can be discharged by auxiliary air cover.

Primary air level flows through the given channel (passage) 38 (see Fig. 7 b) be made up of the polypropylene section that thin-walled is extruded.Water is replacing flowing (Fig. 9 b) from top to bottom in secondary-air passage 42, and secondary waste gas then flows from bottom to top in this two subchannels 42, therefore can realize the lateral flow function of sensible heat exchanger like this.

As shown in Fig. 2, Fig. 3 and Fig. 4, immersible pump 16,17 can flow to distribution sleeve 19,21, to guarantee to spray water smoke equably respectively above HE-I DAMA 7 and HE-II 8 by polymer pipeline 18,20 water from water tank 14.And a kind of operating UV system can continue to make recirculated water keep disinfection.

As shown in Figure 5, filter and cool/treated primary air 25 flows through the living space 29 being about to carry out cooling, conversely, primary air can be absorbed the heat in living space 29 and be discharged by the gas extraction system 28 be equipped with in the enclosure space 29 that is about to carry out air conditioning.

Whole process by based on control system can perceive signal and can operate/preprogrammed microprocessor 30 (as Figure 11) of control system controls.When opening system, controller can detect in water tank 14 whether have enough water, once reach suitable water level, so system will start water pump 16,17 and run certain hour, so that the spunbonded nonwoven in the water disinfection in UV system 22 pairs of water tanks and evenly humidification HE-I DAMA 7 heat exchanger and the medium in HE-II heat exchanger 8.Subsequently, system can start air blast 3, to order about filtered air 23 flowing through heat exchanger.

Preprogrammed microprocessor 30 (see Figure 11) controls all functions of system.As shown in Figure 5, primary air flows through the living space 29 being about to carry out cooling.Microcontroller 30 can pre-set the temperature required and relative humidity (hereinafter referred to as Rh) in living space.Along with whole system starts to enter running status, signal/control inerface 75 also receives temperature from space 29 and Rh signal gradually.(microcontroller 30 can receive preset temperature and the Rh of regulation.) if humidity is controlled, so microcontroller can change with the comparable situation of physical condition the discharge flowing through direct heat exchanger according to pre-conditioned, if and temperature is controlled, so microcontroller can change air capacity according to pre-conditioned with the comparable situation of physical condition.System can compare the temperature perceived and Rh signal and the pre-conditioned of regulation, and also can regulate humidity and/or air capacity, until the temperature of perception and Rh are equal in fact (being within the scope of engineering tolerances) temperature and/or Rh.In addition, microcontroller also can run the exhaust fan of requirement according to current needs.

In certain example, one or more processor 30 may comprise server and client side's processor, computer usable medium then comprises for performing and supporting that (this software may include but not limited to as DCOM or CORBA or the webserver/browser and third-party application the necessary component software of Distributed Application telemanagement of the assembly of indirectly/direct evaporating-cooling device disclosed in the utility model, as ColdFusion ^tM/ ShockWave ^tM).

Although be described in detail the utility model by various embodiment, it is noted that the utility model also comprises be in various modification in the utility model intention and scope and other embodiment.
