### Objectives:-

• To maintain the temperature and humidity conditions in a closed environment.
• To maintain the life cycle of BSF throughout the year.

In July literature reading of Black soldier fly.DId some phychometric calculation for maintaining temperature and humidity.

After that we collected worms and setup in usage for further life cycle.

Put the worms in stand based trays with food.

### Humidity calculation:-

Humidity:-

• Humidity is the concentration of water vapour present in air.
• If humidity is low water holding capacity is high.

Dry bulb temperature (DBT):-

• If DBT increase the capacity of moisture and the airspace will also increase.

Wet bulb temperature (WBT):-

• Wet bulb temperature is measure of the cooling efficiency.
• At 100% relative humidity the WBT equals DBT.

Relative humidity (RH) :-

• It determined by comparing the WBT & DBT.

Dewpoint:-

• Dewpoint temperature is close to the Air temperature when RH is high.
• And if Dewpoint is well below the air temperature RH is low.

In august we made 2 separate setup for cocoons and flies in dome.

### Dome calculation:-

Prototype setup:-

Required material

• Table for stand
• Mosquito net
• Green net
• Black sheet
• Plastic trays
• Lamp
• Cooler

### Maintain humidity and temperature sector:-

After all this we put cooler for maintaining humidity and temperature.

we take calculation with fan pad of cooler with 2″ pads and we did this calculation in two domes and we got efficiency like,

Dome 1:- 46% and

Dome 2:- 33%.

After that we get trial with 4″ pad and we got efficiency like,

Dome 1:- 83%

Dome 2:- 81%

There are some reading of humidity and temperature taken by me before running cooler and after running cooler,

Before running cooler at 2:20 pm

After running cooler for 1 hour at 3:20 pm

Then we increase the time duration of reading to 1:30 hours and data be like at 10:10 am

After running cooler for 1:30 hours at 11:40 am
