Hotel energy consumption peaks during summer when full occupancy and high temperatures place significant strain on energy supply systems. Due to the heat and increased number of guests, air conditioners and cooling systems operate at maximum capacity to ensure guest comfort. High temperatures necessitate not only the cooling of guest rooms but also the maintenance of suitable temperatures in common areas, restaurants, conference rooms, wellness sections, and other service areas.
This intense energy consumption increases hotel operating costs and strains energy supply systems. During peak periods, the additional consumption often results in higher energy bills for hotels, especially if energy use is not optimized. Enhancing cooling system efficiency and implementing energy storage solutions becomes particularly important during the summer months. Technologies like cooling energy storage can help reduce peak period loads by allowing for more efficient energy use and storage during periods of lower consumption.
By installing an Intelligent Thermal Battery, the Hotel can save nearly 20% on energy annually, which represents significant savings for the hotel.
Storing cooling energy enhances the efficiency, lifespan, and reliability of cooling systems. The thermal battery can be charged under the most efficient conditions: at low external temperatures and with the cooling system operating at optimal partial loads. During discharge, the chiller and HeatTank work together to meet cooling demands, saving not only the electricity proportional to the HeatTank's storage capacity but also increasing the chiller's efficiency due to optimal partial load operation.
The following diagram illustrates daily cooling demand before and after installing the HeatTank thermal battery. It shows that during peak times, the HeatTank and the cooling system jointly meet the demands, while at night, the HeatTank thermal battery recharges under better cooling efficiency conditions.
Reducing peak demands allows for the reduction of contracted electricity amounts and makes electricity use more flexible. This increased flexibility enables the exploitation of electricity price differences and easier integration of renewable energy sources into the system (e.g., solar panels). These opportunities significantly accelerate the return on investment.
