Thread-topic: [TRNSYS-users] How to control absorption chiller (Type 107)

Dear Angel,

Do you mean combine 2 conditions into equation block and then use these result to control absorption chiller (type 107) right?

If yes. Could you tell me how can i combine both into equation block?

I'm looking forward to hearing from your answer.

Thanks.

Best regards,

Sinchote

Dear Sinchote,

You can implement that control by multiplying both of your conditions in an equation block, and use the result as your control signal. The first of your conditions will work better if you implement it in a type 2 and the second can came from some forcing function, hope it helps

Dear Trnsys users,

I'm studying in master degree and conducting the simulation solar cooling system. I have a problem about how to control the absorption chiller model(type 107) working.

I would like to control 2 modes for absorption chiller working :

1. Absorption chiller working when temperature in hot water tank reach to 75 degree celsius and

2. Absorption chiller working on 9.00 a.m. - 22.00 p.m.

The absorption chiller wiil work when both of conditions happen.

Has anyone experienced this problem and knows how to fix it?

Best regards,

Sinchote
