6 FAQs about [Principle of cold water energy storage air conditioning]

What is cold energy storage in air conditioning systems?

In this review, we will mainly introduce cold energy storage applied in air conditioning systems. Compared with the conventional air conditioner, cold storage air conditioning has an additional energy storage tank, which is connected to both the evaporator and heat exchanger in parallel.

How a cold storage air-conditioning system works?

Due to the notable advantage in the specific heat of water compared with air, the latter plays a significant part in space cooling application. In such cold storage air-conditioning systems, the PCM is filled into a cold storage device which is placed in the chilled water side of the system, as shown in Fig. 1.

Can cold thermal energy storage improve cooling system reliability and performance?

The integration of cold energy storage in cooling system is an effective approach to improve the system reliability and performance. This review provides an overview and recent advances of the cold thermal energy storage (CTES) in refrigeration cooling systems and discusses the operation control for system optimization.

Can a water storage cooled air conditioner reduce energy consumption?

Coupling the cold storage unit in the cooling system effectively reduces consumption. For instance, Nguyen et al. realized the cooling of a 400 m 2 workshop by retrofitting a 105.5 kW capacity water storage cooled air conditioner, reducing running costs and greatly improving energy conversion efficiency.

Why is cold storage air conditioning important?

For example, the application of cold storage air conditioning can realize the peak of electricity, thus greatly alleviating the problem of large electrical load during the daytime in summer . However, it requires continuous energy input, and the system complexity is higher.
