Residential Space Heating & Cooling

Hot water is a must-have for hotels, and making sure guests always have it, just the way they like it, is crucial. We get that hotel traffic changes, so we set up 30 big 500-liter tanks to store enough hot water for a whole day. Plus, we added four heating tanks and four 10P hot water units. This setup means guests get hot water whenever they want, at a consistent temperature. It’s all about keeping guests comfy and happy throughout their stay. This upgrade is our way of making sure the hotel stands out for all the right reasons.

Ultra Energy-efficient Operation:

The system operates with remarkable energy efficiency, achieving a coefficient of performance (COP) of 4.4 when heating water from 15°C to 55°C. The electricity consumption for producing one ton of hot water is 10.6 kWh. Compared to traditional open-loop heat pump hot water systems, the annual operating costs can be reduced by up to 40%.

Low Energy Consumption:

The pressurized hot water module maintains water outlet pressure equivalent to municipal water supply pressure, eliminating the need for additional boosting pumps. This reduces system energy consumption, ensures a balance between hot and cold water pressures at the end, and facilitates easier temperature adjustments.

Stable Water Temperature:

Whether in the process of using hot water or heating cold water, the system handles cold and hot water separately, maintaining a constant supply water temperature at the set value.

Easy Installation and Flexible Site Selection:

The system allows for flexible site selection, with water tanks capable of being connected in series without being limited by the site. This enhances the ease of installation and the effectiveness of usage.

Modular Combination:

The system supports modular combinations, where a subsystem failure does not impact subsequent water tank hot water storage. It operates efficiently in winter with slow frost accumulation, and main unit defrosting does not affect the supply water outlet temperature, ensuring constant water temperature.

Quality Products for Enhanced Experience:

Tongyi Air Energy’s pressurized hot water system not only reduces operational costs for the hotel but also enhances the overall service quality, adding luster to the hotel’s offerings.
