Phase change cold storage methods have been used in air-conditioning systems driven by low grade energy, such as solar absorption and adsorption cooling systems. In order to increase the COP of such systems, the chilled water is usually controlled to maintain a temperature higher than that of a system driven by electricity.

Efficient Refrigeration and Air-Conditioning Systems

The AHU consumes more power than chiller because the AHU is equipped with a three-phase fan motor driver and the chiller is equipped with components (compressor, fan, pump) having monophase motors. The electrical consumption of the FCUs is below 5% of the total consumption of electricity in the system (14.97 kWh).

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…

The energy flow density of soil is small, 20–40W/m 2, generally 25W/m 2. This determines that when the soil is only used as the low-level heat source of the heat pump, its load should not be too large. Generally, it is only used when the load is no more than 1 MW. In addition, ground source heat pump has certain area requirements.
