What modification of structure, the change of proportionate relationship or adjustment of size, is not influencing effect and the institute that the utility model can be generated
Under the purpose that can reach, it should all fall in the range of the revealed technology contents of the utility model can be covered.And this practicality is new
Identical label appeared in each attached drawing of type represents identical feature or component, can be applied in different embodiments.
As shown in Figures 1 to 4, the utility model provides a kind of fresh air directly natural Cooling Air-conditioning System, including air-supply system
System 1, exhaust system 2 and central air-conditioning system 3；The supply air system 1, exhaust system 2 and central air-conditioning system 3 combine structure
Into the circulatory system.
In general, production equipment caloric value is big, production technology has environment temperature the factory of strict demand, workshop all directly to adopt
Run throughout the year with conventional central air-conditioning system 3 to freeze.But conventional central air-conditioning system 3 was using
There are the problem of operation expense is high, safety in operation is poor and stuffy for journey.
The direct Cooling System of fresh air provided by the utility model is new on the basis of conventional central air-conditioning system 3
Fresh air supply system 1 and exhaust system 2 are added, to solve the problems, such as that central air-conditioning system 3 exists in use.
During summer, since outdoor temperature is higher, indoor environment directly can be operated to by central air-conditioning system 3 and cooled down, and blown
System 1 and exhaust system 2 are out of service.In the winter time, during spring and autumn transition season, central air-conditioning system 3 is closed, while open and send
Wind system 1 and exhaust system 2 to cool down for indoor environment, to reduce operation energy consumption and the operation that central air-conditioning system 3 is brought
Expense.
In practical applications, the direct Cooling System of the fresh air can be applied to some factories or workshop at the same time.
For example and without limitation, in the utility model, two cars of 1#, 2# are applied to the directly natural Cooling Air-conditioning System of the fresh air
Between exemplified by illustrate, as shown in Figure 2.
Further, in the specific implementation, for example and without limitation, one group of collection can be arranged in two workshops of 1#, 2#
Chinese style air-conditioning system 3, and according to air output and exhaust air rate, arrange some groups of supply air systems 1, some groups of exhaust systems 2.
As shown in Figure 1, the central air-conditioning system 3 includes water cooled chiller 3-1, chilled water pump 3-4, cooling water pump
3-5, cooling tower 3-6, chilled water pipeline 3-7, cooling water pipeline 3-8,1# workshops the first air-conditioning box 3-9 are some, 2# workshops second
Air-conditioning box 3-10 is some；The water cooled chiller 3-1 includes the condenser 3-2 and evaporator 3-3 connected by pipeline.
Further, condenser 3-2, cooling water pump 3-5, cooling tower 3-6 pass sequentially through cooling water pipeline 3-8 and form closed loop company
Connect；The close loop brings the condensation heat of kind of refrigeration cycle to cooling tower 3-6 by the water that is cooled after condenser 3-2 heat exchange, passes through
Cooling tower 3-6 will condense heat produced into air.
Further, evaporator 3-3, chilled water pump 3-4, some first air-conditioning box 3-9, some second air-conditioning box 3-10 be successively
Closed loop is formed by chilled water pipeline 3-7 to connect.In general, compressor and expansion valve have been further included in water cooled chiller 3-1, and
Evaporator 3-3, compressor, condenser 3-2, expansion valve in water cooled chiller 3-1 are sequentially connected with by pipeline.When the water
During cold handpiece Water Chilling Units 3-1 operation, water cooled chiller 3-1 using electric as power source, it is and preset in its evaporator 3-3
There is freon refrigerant, the heat that freon refrigerant evaporates absorption refrigerating medium water in evaporator 3-3 freezes, and evaporation is inhaled
Freon moist steam after heat is compressed by the compressor into high temperature and high pressure gas, becomes liquid after condensed device 3-2 condensations, then through swollen
Swollen valve throttling, which enters in evaporator 3-3, to be recycled；It is for air-conditioning box 3-9, air-conditioning box 3-10 so as to produce 7 DEG C of -12 DEG C of chilled waters
Indoor environment cools down.The central air-conditioning system 3 is run when summer, outdoor temperature was higher, is cooled down for indoor environment, in the winter
Season, spring and autumn transition season outdoor temperature are out of service when relatively low, to save operation energy consumption and operating cost.
The supply air system 1 both may be mounted at interior according to practical situations, can also be installed outdoors；
In the utility model, to be illustrated on 1 roof installed outdoors of supply air system.
As shown in figure 3, the supply air system 1 is implemented in roof, and it is uniformly distributed in each site in roof, each site
Connected by pipeline and unified air outlet is set after planning, or be individually formed some air outlets.Further, the air-supply
System 1 includes sequentially connected fly net 1-1, rain cover air hose 1-2, air inlet valve 1-3, air box 1-9, outlet valve 1-6, air-supply
Pipe 1-7, air outlet 1-8.Wherein, the air inlet of rain cover air hose 1-2 is downward；Pressure fan 1-5, wind are configured with air box 1-9
The inlet of cabinet 1-9 is provided with primary filter 1-4；Ajutage 1-7 runs through roof, the air outlet of ajutage 1-7 outlet air ends
1-8 is downwards and positioned at interior.
As shown in figure 4, the exhaust system 2 includes exhaust blower 2-1 and self hang down type blinds 2-2, and self hang down type blinds 2-2
Positioned at the air outlet of exhaust blower 2-1.For example and without limitation, exhaust blower 2-1 can be that axial flow blower can also be centrifugation wind
Machine, the utility model is by taking axial flow blower as an example.In a preferred embodiment, the exhaust outlet of the exhaust system 2 is located at outside room
The top of wall, in order to exclude the hot-air of room upper space to outdoor；It is because indoor in the winter time with spring and autumn transition season
Equipment heating amount is also very big, indoor temperature it is also higher, and outdoor temperature is relatively low, also needs to give indoor environment cooling.
When exhaust blower 2-1 is operated, the self hang down type blinds 2-2 of exhaust blower 2-1 air outlets is automatically opened up, room upper space
Hot-air exclude to outdoor；When exhaust blower 2-1 is shut down, self hang down type blinds 2-2 is automatically closed.Meanwhile outdoor low temperature is new
After wind is inhaled into rain cover air hose 1-2 after fly net 1-1 filterings, primary filter 1-4 mistakes are entered via air inlet valve 1-3
After filtering dust collecting, pressurizeed in pressure fan 1-5, sent again via blow valve 1-6 by ajutage 1-7 and air outlet 1-8 after pressurization
Enter interior, providing cold air for indoor environment cools down.
The supply air system 1 and exhaust system 2 in the winter time, spring and autumn transition season outdoor temperature it is relatively low when run, be room
Interior environment temperature reduction, it is out of service when summer, outdoor temperature was higher.
The technical solution of the utility model, for example and without limitation, has the advantages that：The fresh air is directly natural
Cooling Air-conditioning System is suitable for winter, spring and autumn transition season and still needs the special occasions that air-conditioning system provides refrigeration duty, can be with
Air-conditioning system operation energy consumption, operating cost and maintenance expense are substantially reduced, improves safety in operation and air conditioning area
Air quality quality, to obtain more considerable Social benefit and economic benefit.
Foregoing description is only the description of the utility model preferred embodiment, is not any limit to the scope of the utility model
It is fixed.Any change or modification that any those skilled in the art makes according to the technology contents of the disclosure above should all
When being considered as equivalent effective embodiment, the scope of technical solutions of the utility model protection is belonged to.
