Hi, Does this system use refrigerant ?like R-410A?or does it only use the chilled water as the mean to cool? if it's does use refrigerant , what would be the significance of it in this system? Thank you. - Dan
@Systemcontroltech8 жыл бұрын
The chiller itself does use refrigerant to cool the water. That water is then used to provide cooling in the air handlers.

Could you please tell me what are the purposes of "DECOUPLER FLOW SWICTH" and "FLOWMETER" in chiller system bypass line/pipe. Thank you.
@Systemcontroltech8 жыл бұрын
+Jarmen Kell I am assuming that you are talking about a system that has more than one chiller? It really depends on your system configuration. We have a system with a decoupler loop that actually uses the flow through the loop to stage up a second chiller. The more chilled water the air handlers call for the more the flow goes negative in the decoupler loop. Once it reaches a certain level, it will bring up the second chiller. I hope this helps but there is a lot of things that the information from the decouler loop can be used to control. This is just one example.
@jarmenkell3858 жыл бұрын
+System Control Tech Yes indeed it helps me a lot thank you so much. Yes you are right this is multiple chillers, using primary-secondary. Could you suggest some references books/websites related to this topic? Thanks.
@Systemcontroltech8 жыл бұрын
+Jarmen Kell Unfortunately I do not know of any references for this type of control sequence. What I've learned about it has been hands on experience. There is a range of operation that will trigger the second chiller depending on the range settings. It is probably buried in the programming on the controller. As the valves on the air handlers open further the secondary chilled water pump ramps up to compensate. This causes a negative flow in the decoupler loop and once the flow goes negative enough, the second chiller is brought online. Good luck.

Does it maintain the set temperature only near the pipes or the entire room?

The temperature will increase the further through the system but keeps it close to setpoint as it enters the coils.

In a condo if floors 8 and below are blowing cold air in the halls and the rest of the floors are ok what can be the problem ?
@Systemcontroltech7 жыл бұрын
+Frank James you have a water balance issue. Cut back the flow to the lower level devices until they just start to not cool effectively. There should be around a 10 degree drop through the coil of the unit. Measure the air temperature before the coil and then after the coil. Set the flow through each unit to where there is a 10 degree drop. That should allow more flow to the upper levels.

@Systemcontroltech8 жыл бұрын
+Kyaw Zin Thant Chilled water systems such as the one described in the video will use a chiller to cool water that is then used to provide cold water to air handlers which provide air conditioning. The cold water is pumped through the chilled water coil on the air handler and cools the air that passes through it.
