How do you calculate chilled water system volume if knowing chiller capacity?
just multiply pump capacity by 3
Why you have to connect the pressurization unit pipes to the pump suction of the chilled water pump and not to discharge header?
As the chilled water system is a close system and basically consist of two loops i.e one loop from pump discharge to load & second loop from load to pump suction.Now,the effect of pressure drop will be more prominent in the second loop ,after the flow exit the load.Hence we have to alleviate the pressure where the effect of pressure loss & small water requirement is more prominent and i.e the suction side of the pump.
Where you put air separator in chiller?
at end of the chilled water return header, before entering in to suction of the primary pump and chiller anand
Flow diagram of chilled water system?
You are probably referring to Absorption refrigeration. Try Google.
Why can you observe water droplets on the surface of a chilled bottle?
You can observe water droplets on the surface of a chilled bottle because the temperature of the atmosphere is a different temperature to that of the temperature in the chilled bottle.

Why are primary chilled water pumps smaller than secondary pumps?
PRIMARY CHILLED WATER PUMPS ARE SELECTED TO FULFILL THE REQUIREMENTS OF THE CHILLER WHERE AS SECONADRY CHILLED WATER PUMPS TO SUPPLY CHILLED WATER TO THE LOAD. FOR EXAMPLE TO THE FAN COIL UNITS & AIR HANDELING UNITS. IN NORMAL PRACTICE THE SECONDARY CHILLED WATER PUMPS ARE APPLIED WITH VARIABLE FREQUENCY (SPEED) DRIVE WHILE PRIMARY WITH CONSTANT SPEED, IN THIS ALSO PRIMARY CHILLED WATER PUMPS CAN BE USED WITH VFD SYSTEM.
