In modern commercial environments, such as large shopping malls, hotels, office buildings and other places, chillers create a comfortable, efficient and energy-saving environment for modern office spaces with their excellent cooling, heating and heat recovery functions.
(1) Centralized Air - Conditioning System: Most office buildings use a centralized air-conditioning system, with the chiller as the core cold source. It generates low-temperature chilled water via compression refrigeration, which is sent to air handling units (AHUs) on each floor. The AHUs exchange heat between the chilled water and air, delivering cooled air to commercial areas to maintain a comfortable temperature.
(2) Localized Hot-Spot Cooling: In machine rooms and data centers of office buildings, chillers provide customized cooling via independent pipelines to precision AC terminals for precise temperature control.
Heating Applications
(1) Winter Heating: Chillers with heating functions can be switched to the heat pump mode. By absorbing heat from outdoor air (or other low - temperature heat sources), after being compressed and heated by the compressor, the heat is transferred to the hot water circulation system. The hot water circulates in the heating pipes of the office building, providing warm air to the office areas. This method is more energy - efficient and environmentally friendly compared to traditional gas - fired boiler heating.
(2) Fresh Air Pre-heat: The chiller pre-heats outdoor fresh air via a pre-heat coil before it enters the air handling unit, mixing it with indoor air. This enhances comfort and saves energy.
Heat Recovery Applications
Domestic Hot Water: The chiller's waste heat is recovered to heat domestic hot water, saving energy and boosting efficiency.
High Energy Efficiency: Chillers feature advanced intelligent control systems that monitor equipment status in real-time and precisely adjust cooling, heating, and heat recovery power output.
Heat Recovery - based Energy Savings: By utilizing waste heat from the refrigeration process, chillers reduce additional energy consumption. This cuts energy costs and carbon emissions, aligning with environmental protection goals.
High Comfort Level: Integrated with centralized air - conditioning systems, chillers provide stable temperature and humidity control with uniform air distribution, preventing local temperature imbalances.
Centralized Equipment Layout: Installed in specific areas like basements or equipment rooms, chillers save indoor office space. Their easy - to - plan and maintain pipelines reduce building space occupation and maintenance costs.
Environment - friendly Refrigerants: Chillers mostly use eco - friendly refrigerants such as R134a and R410A to minimize environmental pollution.
High Equipment Reliability: With compressors and electronic components from reputable brands and strict quality inspections, chillers offer high reliability and stability.
Low Noise: Chillers have low operating noise, with main noise sources confined to machine rooms or basements, causing minimal disturbance to commercial areas.
