Ice storage air conditioning

OverviewEarly ice storage, shipment, and productionAir conditioningCombustion gas turbine air inlet coolingSee also

Ice storage air conditioning is the process of using ice for thermal energy storage. The process can reduce energy used for cooling during times of peak electrical demand. Alternative power sources such as solar can also use the technology to store energy for later use. This is practical because of water''s large heat of fusion: one metric ton of water (one cubic metre) can store 334 megajoules (MJ

What is a Pump?

A pump is a mechanical device, that is used to pick up water from a low-pressure level to a high-pressure level. Basically, the pump changes the energy flow from mechanical to fluid. This can be used in process operations that need a high hydraulic force. This process can be observed within heavy-duty equipment.

The Working Principle Heat Pumps | Green Energy Solutions

The Working principle. Heat energy naturally transfers from warmer places to colder spaces. However, a heat pump can reverse this process, by absorbing heat from a cold space and releasing it to a warmer one. Heat is not conserved in this process and requires some amount of external energy, such as electricity.
