Free Cooling 
Why pay to run a power-hungry mechanical cooling system to chill something to 15°C when the outside air temperature is 5°C? When year-round cooling is required, it can often be achieved using ‘free cooling’; that is, cooling without using a refrigeration circuit. Free cooling takes advantage of low-season ambient air temperatures to directly cool the process fluid, supplementing or even replacing a refrigeration system when air temperatures permit, and can save on running costs making it good for the environment as well as your pocket. 
Energy Recovery 
Refrigeration systems work by removing heat from the chilled space and rejecting it elsewhere, usually to the outside air via a heat exchanger. This ‘wasted’ heat can be recaptured and used to satisfy other heating requirements nearby. Think of a professional gym: there is an air cooling system for the comfort of the gym users, and a boiler to heat the water for the swimming pool and showers. A well designed heat recovery system would use the heat gathered from the gym to heat the pool and shower water, thus reducing or eliminating the need for a separate boiler, and its associated running costs. 
Ice Banks  
TES has developed accelerated ice building units "Ice Banks" that take full advantage of the remarkable cost savings available from off-peak electricity and the convenience of times of low demand. In overall performance the TES Ice Bank is unequalled for versatility and flexibility.
