Detailed Description

Example 1: clean room between bilateral distributed heat sources

Referring to fig. 1 and 2, the clean room of the embodiment includes a high-precision constant-temperature clean zone 10, the temperature control precision can reach ± 0.01 ℃, and the cleanliness can reach hundreds or even ten levels; in the high-precision constant-temperature clean zone, an apparatus 11, such as a laser in an optical laboratory, which has extremely high requirements for temperature control precision and cleanliness is placed. Arranging common constant-temperature cleaning areas 20 at two sides of the high-precision constant-temperature cleaning area, controlling the temperature with precision of +/-1 ℃, and keeping the cleanliness at thousand or hundred; heat source devices 21, which are larger heat sources, are placed with somewhat lower requirements on temperature control accuracy and cleanliness. Therefore, the arrangement is a distributed clean room design, and the area of the common constant-temperature clean area 20 is a constant-temperature clean working area and is also a return air channel, so that a separate return air shaft is omitted. Meanwhile, as the large heat source equipment is placed in the common constant-temperature clean area 20, the airflow direction determines that air enters from the high-precision constant-temperature clean area 10 through the air return opening 22 and enters the upper technical interlayer 30 from the air return opening on the top 23, heat generated by the heat source equipment 21 is brought into the upper technical interlayer 30 by the air return flow, and the temperature and humidity of the upper technical interlayer 30 are adjusted by the air conditioner internal unit 31 and the dehumidifier 33 and then enter the high-precision constant-temperature clean area 10 through the air outlet of the fan filter unit FFU 32. The distributed design not only saves space, but also avoids the fluctuation of the temperature of the high-precision constant-temperature clean area 10 caused by the heat generated by the equipment. The high-precision constant-temperature clean area 10 area and the common constant-temperature clean area 20 area can be communicated through an equipment door. If the connection between the equipment 11 requiring high-precision constant temperature and the heat source equipment 21 is required, a through-wall hole can be arranged on the partition wall.

Whether the temperature of a factory building/laboratory can be kept stable or not is related to the configuration of an air conditioner, the external environment and the heat released by the dynamic working environment of the laboratory. So the utility model discloses a design can get into technical interlayer 30 by the heat of heat source equipment 21 release, and does not bring the temperature fluctuation for high accuracy constant temperature clean area 10 region, can realize regional very high accuse temperature precision (+/-0.01 ℃).

In addition, the present embodiment has a redundant and energy efficient design. The same refrigerating output demand, constant temperature and humidity purification air conditioning unit is adopted to traditional toilet, and the embodiment adopts a plurality of components of a whole that can function independently variable frequency air conditioner. On one hand, the design is redundant, and when one air conditioner has problems, other air conditioners work normally, so that the normal operation of the whole clean room system can be ensured; and secondly, energy is saved, because the external environment temperature is low in winter, the refrigerating capacity required by the clean room is also low, and at the moment, the refrigerating requirement of the whole clean room can be met by closing 1 or more air conditioners and only keeping the minimum number of the air conditioners. Because of adopting the frequency conversion air conditioner, the refrigerating capacity output can be controlled in multiple steps according to seasons, and the purpose of saving energy consumption is achieved; according to estimation, the utility model can save electricity cost by about 5-10 ten thousand yuan/year compared with the cleaning room of the traditional constant temperature and humidity air conditioner in a cleaning room with 60 square meters.

Example 2: clean room between unilateral distributed heat source

Referring to fig. 3, the present embodiment is different from embodiment 1 in that: a common constant-temperature clean area 20 is arranged close to one side of the high-precision constant-temperature clean area 10, a channel return air cavity 40 is arranged on the opposite side of the common constant-temperature clean area 20, return air enters from a return air inlet 22 and returns to the upper technical interlayer 30 from the channel return air cavity 40. The design can ensure that the return air is symmetrically and uniformly distributed, and the airflow inside the clean room is laminar rather than turbulent. The width of the channel return air cavity 40 is 5 cm, so that the area of the ground is saved compared with that of a traditional return air shaft (usually larger than 60 cm), and the utilization rate of the ground is effectively improved.

Example 3: energy-saving noise-reducing clean room with upper-technology interlayer distributed design

Referring to fig. 4, the basic configuration is similar to that of embodiment 2, and on the basis of embodiment 2, the upper technical interlayer 30 is designed in a distributed manner, so as to achieve the purposes of further reducing the cost, saving the energy consumption, and improving the performance index (especially, noise isolation and uniform air flow). Between the upper technical interlayer 30 and the high-precision constant-temperature clean zone 23, an air outlet interlayer 34 is further separated, and the height of the air outlet interlayer can be 40 cm under the condition that the height of the laboratory/factory building layer allows. The top of the air outlet interlayer 34 is fixed with a fan 35, the lower part of the air outlet interlayer is fixed with a fan filter unit FFU32, air which is subjected to temperature and humidity adjustment by the air conditioner internal unit 31 and the dehumidifier 33 of the upper technical interlayer 30 enters the air outlet interlayer 34 through the fan 35, is fully and uniformly mixed in the air outlet interlayer 34, is filtered by the high-efficiency filter 36, and then is blown downwards to the high-precision constant-temperature clean area 10.

Through the cooperation use of fan and air conditioner, can set for power, the fan setting mode of air conditioner according to external environment, each regional actual need in the clean district, therefore pressure distribution, humiture etc. of different regions in the adjustable clean district make the clean district have higher cleanliness factor simultaneously, have reduced the working cost, have improved operational environment, provide the ultra-clean environment for production and scientific research.

This distributed top sandwich design may have three advantages: 1. overcome traditional FFU's shortcoming, FFU is that a fan corresponds a high efficiency filter, the utility model discloses separately place fan and high efficiency filter, the quantity of fan can not be equal to high efficiency filter quantity, for example in figure 3, 4 high efficiency filters only need 2 fans, have lacked 2 fans than traditional FFU mode, have played the effect of practicing thrift the fan (also practiced thrift cost and energy consumption). 2. Compare with traditional FFU, reduced the noise, because FFU's (fan) snap-on is on the furred ceiling, and the utility model discloses a fan is fixed on the baffle of the one deck of going up again of furred ceiling (also be exactly the interbedded roof of air-out), has more one deck baffle and an air buffer layer (air-out intermediate layer) than FFU that kind of mode, has played and has fallen the effect of making an uproar. 3. Because the wind that the fan came out can be abundant mixing at air-out intermediate layer 34, so the space homogeneity of temperature is better, and the wind that blows out from high efficiency filter is more even.
