1. Telecom Shelters:
Telecom shelters are insulated, air-conditioned
enclosures that house the heart of mobile communication, the Base Transceiver Station (BTS). BTS,
and also the battery, is very temperature sensitive and its surroundings should always be
maintained below 35 deg C. In under-developed countries, there are frequent power cuts and single
phasing, forcing cellular service providers to install Diesel Generators to support the
air-conditioner in case of power cuts or single phasing. Phase Change
Material PCM installed in Telecom Shelter will
absorb heat in case of unavailability of power, minimizing/eliminating use of DG Sets. PCM will get
re-charged when power source is available. Thus, PCM store energy using a cheap source of power
and release it when that cheap source of power is not available, thus saving on Diesel Cost.

2. Transportation:
Transportation of perishable foods, temperature sensitive pharmaceuticals,
sundry electronics (like ignition transformers) and chemicals (explosives) require refrigerated
trucks. Such refrigerated trucks are prohibitively expensive to operate as they use Diesel as a source of
energy. Cost of diesel-generated energy is 6 times higher as compared to conventional electricity
cost. Thus, Phase Change Material store energy using a cheap source of
power and release it when that cheap source of power is not available.

Automobiles
PCM
is already used today in a latent heat battery offered by BMW as optional equipment in its 5 series.
The principle is quite simple, the storage material is connected to the radiator and stores excess
heat when the motor runs at operating temperature. This heat is then available at the next cold
start to heat up the motor quickly (better gas mileage) and for the interior (driving comfort). Due
to the latent heat battery’s excellent insulation, it can maintain the energy for 2 days at an
outside temperature of – 20 °C. As an extension to this application, PCM can also be used in
tail-pipes (exhaust) of vehicles. This will maintain the catalytic converter at its design
temperature, reducing excessive Hydro-carbon emissions during vehicle start up.

House heating, warm water:
Solar
energy is not available at all times, and therefore solar installations require an intermediary
storage of the energy for heating or warm water. PCM based system will offer the following benefits
over a conventional system: Low volume in comparison to water storage systems and a higher
efficiency due to a lower temperature difference between loading and discharging of the energy.
Latent heat storage can also be implemented in conventional heating systems.
Phase Change Material based solar water
heater will also give a better controlled water temperature.

Construction materials:
The
atmosphere in a room is found comfortable if it varies little in the course of the day. For this
reason, homes with very thick walls are found especially comfortable: cool in the summer and warm in
the winter. To achieve this comfort in less massive constructions, one can implement materials
containing PCM and thus demonstrating the same properties as thick walls. By absorbing heat at the
peaks (e.g. during sunshine) and delayed release in the night, in most cases one can even do without
air conditioning.
6.
Catering:
The
transportation of warm meals requires a heat source; otherwise it will not meet the quality
standards set by the consumers. An electric heating source cannot always be implemented, in such
cases Phase Change Material offer an ideal, self-regulating heating element. The melting point of the
PCM depends
upon the temperature at which the food should be kept. 60° – 70°C are optimal so that the food does
not continue to cook but is hot enough to eat.
7.
Electronics:
Electronic circuitry is extremely sensitive to over-heating, negatively influencing both lifetime
and reliability of the parts. To date, metal fins are used for heat sinking improving their cooling
capacity with additional fans. The sinking of heat peaks using PCM is absolutely reliable since no
motor or temperature measurements are required. The PCM regenerates itself between peaks by emitting
the heat with cooling fins. The advantage is a smaller cooling system with a very high reliability.

8. Green Houses:
It is important to maintain temperatures in a small
range to enable plants cultivated in a green house to flourish. However, due to large temperature
swings in daytime and nighttime temperatures, most green houses need air-conditioning and/or
heating. Phase Change Material installed in floor of such green houses will eliminate or reduce the dependence on
air-conditioning/heating. link on column 2.
9. Temperature Peak Stabilization:
In the chemical industry, there are applications
where refrigeration and heating are required in the same batch. In such cases, use of PCM will
reduce utility costs, as PCM will store energy from the chemical reaction for use at a later stage
in the same batch.
