Distribution of the programs
Where brains?
Please clear the following situation.
We have the freely programmed controller (s),and
we have the computer with the scada-program, which exchanges the data with the controller. In the controller is placed the executed program,but in the computer...
Hi elfman!
Though you don't specify an exact arrangement of air supply grilles, it is supposed that some of them are located below.
I think it is useful to check up the air stream from them simple by a hand. Be sure that is not present any obstacles for it passing.Many of grilles have...
Dear SAC9!
That I've caught.
In connection with a condition that you want to ensure
constant flow of exhaust air by means of baypass you will take a part of air passing HERA filters.
In such case it will result in incorrect work of these filters.
Concerning control of the damper I can offer...
In first I want to thank dear KenRo
for his attentive amendment.Sorry, Now all is correct.
Further, concerning a discussed theme, I shall state some more small remarks.
It is doubtless, that the value, laying in limits from 0,35 ANI to 0,6 ANI is closest for home application,however it is...
Hi sam42!
Some more information...
From the building code perspective,
adequate ventilation refers to that level of ventilation that protects the health and safety of its occupants. Most regions of the U.S. have building codes that specify
ventilation levels for new buildings. Some regions...
Hi!
The technological process works with sharp rises of temperatures.(10F/20s)
It's necessary to mix water so that:
1. Occurred initial heating of water practically immediately - for activation of chiller's loading system
2. The change from a minimum to a maximum must occured extended in...
Hi all!
CHWS for process aplication
What best way of an arrangement pipes of input
and output in buffer tank for obtain of gradual change temperature, at heat impact from loadings (at one level, one is higher than another, to arrange above, below, in middle)?
How to calculate its(tank)...
This question is connected to a method of regulation the necessary difference pressure on evaporator in case of small heat loading,
but plenty of the consumers . The variant is considered
for VarPrOnlySys. Unique, that anxieties me,
it's passage of the cooled water through evaporator. I...
I think it's might be so:
Required flow can be calculated according to
Q = H/c*p*(Ti - To)
assume that
H = 205kWt or 11658 Btu/min,
c = 0.24,
p = 0.075,
Ti = 30C or 86F,
To = 40C or 104F,
and Q = only 35981 CFM.
Hi bundy!
1. The real chiller's capacity can vary depending on loading.
2. Try to use the following formula:
TR = Flow(l/s) x Evap.Range(deg C) x 4.187 x 0.2844
Hi all!
As is known, obligatory attributes, necessary at installation chiller,
are so-called shoot-off valves.
I am not quite sure, but I assume,that it's made for when chiller does
not work, the pump consumed smaller power (1), and that the cooled
water did not proceed through...
