Description
Technical field
The present invention relates to laboratory field, a kind of laboratory with constant temperature and constant humidity is particularly related to.
Background technology
Laboratory with constant temperature and constant humidity is that, by some special equipments and technical method, its interior is met the experiment such as warm, wet will
The laboratory asked, laboratory with constant temperature and constant humidity is the infrastructure that material and product quality inspection are checked on.Existing constant temperature and humidity is real
Room air blow and return mode is tested from upper blasting floor air return method, air-supply is sent into laboratory by airduct through air diffuser, and return air leads to
Cross raised floor and be back to air-conditioning return air system.Because laboratory with constant temperature and constant humidity is the occasion of someone's work, staff is in experiment
During need often to walk about, and laboratory domestic demand installs more highly sophisticated device, and raised floor has easy laying dust, stably
Property difference the shortcomings of.Moreover, in order to ensure laboratory with constant temperature and constant humidity in laboratory with constant temperature and constant humidity humiture index request, current industry
Control system is carried using air-conditioner set more than control system, the air-conditioner set of prior art carries control system, belongs to static control
System processed, after laboratory with constant temperature and constant humidity air-conditioning system is installed, directly uses and carries control system progress Laboratory Temperature humidity
Norm controlling.
Specific shortcoming is as follows：
1. airflow circulating low intensity, local wind speed are big, warm and humid uneven：Use in the prior art and above send lower return air stream group
Mode is knitted, air-flow enters in laboratory from laboratory top air diffuser, and the raised floor from laboratory bottom is back to air-conditioning and returned
In wind system, air-flow is, from the upper vertical trend under, not carried out in laboratory internal abundant in the trend of laboratory internal
Circulation, also, air-supply is to be sent into by airduct through air diffuser in laboratory, air diffuser position is fixed position, sends into laboratory
Air the excessive situation of local wind speed occurs through air diffuser, the uniformity to laboratory with constant temperature and constant humidity humiture can not be protected
Card.
2. easy laying dust：On send lower return air stream organizational form be traditional air current composition mode, more be applied to computer machine
Room (unattended), computer room needs to arrange many control lines under antistatic, floor, and raised floor is optimal
Settling mode.In the laboratory with constant temperature and constant humidity for thering is lab assistant to work, the rubbish for the generation that usually works and personnel's walking production
Raw dust is deposited on below return air floor through return air inlet, and slight dust can be circulated in the wind does not stop migration in room, to personnel
Physical and mental health causes harm.
3. stability is poor：On send lower return air stream organizational form to form return air storehouse using raised floor is built on stilts, due to overhead
Floor stability is poor, is not suitable for laying high precision instrument on hanging ground, and can not do stability experiment room, in use
Have some limitations.
4. closing, anoxic：Existing laboratory with constant temperature and constant humidity is enclosed environment, using precision air conditioner to the temperature in laboratory
Degree and humidity are adjusted, however, laboratory worker is chronically in so special enclosed experiment room environmental, easily lead
The bad reflections such as staff's anoxic, agitation are caused, Comparision constrains.
5. existing control system is static cost control, this control mode is applied to computer room, it is not necessary to introduce fresh air,
The situation that usually few personnel come in and go out, it is impossible to meet laboratory resh air requirement demand, fresh air or laboratory are introduced there is laboratory
Personnel's turnover instant airflow disturbance can cause Laboratory Temperature moisture fluctuation, and Ability of Resisting Disturbance is poor；
6. existing control system Temperature Humidity Sensor position is sent back at air port installed in air-conditioner set, sensing humiture change
Situation is limited in scope, and humiture change of the laboratory with constant temperature and constant humidity at away from air-conditioner set return air inlet can not timely be felt
Know, control accuracy is low；
7. existing control system humiture is shown on air-conditioner set, usually laboratory operation personnel can not can be visually seen
Laboratory Temperature humidity changes.
