<v ->Chillers provide crucial cooling for air conditioning</v>

00:00:06.870 --> 00:00:10.590
and refrigeration, but they also use a lot of energy.

4
00:00:10.590 --> 00:00:13.410
Optimize your operations with these low-cost strategies

5
00:00:13.410 --> 00:00:16.380
to improve chiller system efficiency and performance.

00:00:16.380 --> 00:00:19.047
(lively music)

7
00:00:20.910 --> 00:00:23.490
Chillers rarely operate at full capacity

8
00:00:23.490 --> 00:00:24.900
and their efficiency drops

9
00:00:24.900 --> 00:00:29.160
as the load decreases, especially as loads drop below 50%.

10
00:00:29.160 --> 00:00:31.470
Monitor the capacity of all your chillers

11
00:00:31.470 --> 00:00:33.150
and manage their load.

12
00:00:33.150 --> 00:00:34.410
For optimal efficiency,

13
00:00:34.410 --> 00:00:38.003
keep all active chillers within the 60 to 80% range.

14
00:00:38.003 --> 00:00:41.310
(lively music continues)

15
00:00:41.310 --> 00:00:42.720
An often overlooked method

16
00:00:42.720 --> 00:00:44.400
for improving chiller efficiency

17
00:00:44.400 --> 00:00:46.140
is managing water temperature.

18
00:00:46.140 --> 00:00:48.240
Let's look at three strategies.

19
00:00:48.240 --> 00:00:50.250
Delta-T is the temperature difference

20
00:00:50.250 --> 00:00:51.930
between the chilled water supply

21
00:00:51.930 --> 00:00:53.820
and the chilled water return.

22
00:00:53.820 --> 00:00:56.580
A low delta-T could force chilled water pumps

23
00:00:56.580 --> 00:01:00.270
to work harder than necessary to produce the needed cooling.

24
00:01:00.270 --> 00:01:02.790
Condenser and evaporator approach temperatures

25
00:01:02.790 --> 00:01:03.930
are important metrics

26
00:01:03.930 --> 00:01:05.880
that can impact chiller efficiency.

27
00:01:05.880 --> 00:01:08.490
Low approach temperatures indicate good heat flow

28
00:01:08.490 --> 00:01:10.173
between water and refrigerant.

29
00:01:11.010 --> 00:01:12.510
Chiller lift is the difference

30
00:01:12.510 --> 00:01:15.420
between the outgoing condensing and evaporator water.

31
00:01:15.420 --> 00:01:17.220
It represents the energy balance

32
00:01:17.220 --> 00:01:20.310
between the cooling tower fan and compressor operation.

33
00:01:20.310 --> 00:01:21.960
Lower lift is better.

34
00:01:21.960 --> 00:01:24.270
Use an energy management system to monitor

35
00:01:24.270 --> 00:01:25.710
and evaluate these metrics

36
00:01:25.710 --> 00:01:28.140
and operate chillers at the optimum efficiency

37
00:01:28.140 --> 00:01:29.445
for every load condition.

38
00:01:29.445 --> 00:01:32.040
(lively music continues)

39
00:01:32.040 --> 00:01:33.720
Don't forget preventative maintenance

40
00:01:33.720 --> 00:01:36.510
and regular tracking to make sure the system continues

41
00:01:36.510 --> 00:01:38.700
to work as effectively as you planned.

42
00:01:38.700 --> 00:01:41.400
By combining low cost operational strategies

43
00:01:41.400 --> 00:01:43.170
with targeted maintenance measures,

44
00:01:43.170 --> 00:01:45.270
you can improve chiller system performance

45
00:01:45.270 --> 00:01:47.964
and save money without a big financial investment.
