Description
Technical field
The utility model relates to the air-supply arrangement of independent ventilation cage tool (IVC), especially a kind of independent ventilation cage tool environment control unit in conjunction with temperature humidity control in the more effective solution cage of the power-saving technology tool microenvironment.
Background technology
In recent years, (Independent ventilated cages, IVC) system is the novel feeding manner of laboratory animal to independent ventilation cage tool, has been widely used in not having in specific pathogenic bacteria (SPF) the level experimental animal room air-conditioning system.
The structure of independent ventilation cage tool (IVC) supply air system mainly contains two kinds at present:
(1) as shown in Figure 1, central air-conditioning system is sent new wind into room 13 by indoor ajutage 2 in the laboratory animal Architectural Equipment, the pressure fan 9 of independent ventilation cage tool (IVC) 12 by cage sent into independent ventilation cage tool from the indoor wind of getting, and is discharged to outdoor by its exhaust duct 6 again.
(2) as shown in Figure 2, the central air conditioning supply air system is sent into new wind respectively in room 13 and the independent ventilation cage tool (IVC) 12 by indoor ajutage 2 and independent ventilation cage tool (IVC) ajutage 4 in the laboratory animal Architectural Equipment, eliminate hot humidity load, be discharged to outdoorly more respectively by indoor exhaust wind pipe 8 and independent ventilation cage tool (IVC) exhaust duct 6, room and independent ventilation cage tool (IVC) are separate.
All there is the complicated and high deficiency of operating cost of air-supply Temperature and Humidity Control in this dual mode; main cause is; (1) because experimental animal room adopts brand-new wind operation usually; air quantity is big; the energy consumption height; can not make full use of the energy of air-conditioning; (2) in order to satisfy the control requirement of temp. and humidity in indoor overall situation and the cage tool microenvironment simultaneously; need in the air-conditioning unit, concentrate cool-down dehumidification, and then heat, and animal species between each room; when the animal change causes indoor load difference in quantity difference or the room; in order to realize desired environmental parameter; usually also will thermal part again be set at system's end in each room, cause cold and hot amount to offset, it is very big to consume energy.Air conditioner system air blast is not the control that directly is subjected to temp. and humidity in the cage tool microenvironment in addition, is difficult to satisfy the control requirement of temp. and humidity in the cage tool microenvironment.
For first kind of mode (Fig. 1), for satisfying the control requirement of temp. and humidity in the cage tool microenvironment, indoor overall situation temp. and humidity must be dropped to lowlyer, caused bigger energy consumption.
For the second way (Fig. 2), because overall situation and the air-supply of cage tool microenvironment are that same system is finished, for satisfying the control requirement of cage tool microenvironment temp. and humidity simultaneously, system must be sent into heater adjusting wind pushing temperature is set on the cage tool branched pipe again, also cause energy consumption bigger.
