A research institute is located in a certain area of southern Jiangsu, with three buildings in the south, middle, and north, including office buildings, laboratories, employee dormitories, canteens, and other functional areas. Faced with the increasing demand for new energy vehicle charging among employees, the research institute has added a batch of charging pile equipment. Although it has facilitated employees, it has caused a steady increase in electricity consumption within the institute. Causing the load on the transformers in the hospital to become increasingly high,

Already approaching the safe operating limit; This not only poses safety risks, but also increases electricity costs. The customer requests the Ankerui technical team to find practical and feasible solutions that can effectively reduce electricity consumption and achieve dual security of safety and energy conservation.

The Ankerui technical team found through research that the central air conditioning system is the main energy consuming equipment in the hospital, with an annual electricity consumption ratio exceeding30%The equipment control is extensive, not only lacking a monitoring platform for operation, but also causing waste in the use of air conditioning, such as not turning off the air conditioning in the next shift and setting the temperature too low.

The Ankerui technical team, combined with existing system configurations, provides an overall energy-saving solution that covers the cold and heat sources of central air conditioning systems and the connected control of end fan coil units.

In the cold and heat sources, give6platform15kWInstall frequency converters for both air conditioning water pumps and ground source water pumps; Connect the air conditioning controller through communication6Taiwan frequency converter and2platform88kWThe ground source heat pump host can achieve remote control of both.

The system's operating temperature, pressure, and other data are collected and transmitted to the air conditioning controllerAcrel-7000The HVAC energy-saving optimization platform uses artificial intelligence load forecasting algorithms to pre regulate the water supply flow of air conditioning pumps and ground source pumps, as well as the set temperature of the host;

UseWhale Optimization AlgorithmUnder the condition of ensuring comfort, the system operates with low power consumption.

Install electric control valves in the water supply branches of the south, middle, and north buildings, and control the platform through a rule-based strategy,

Open the valves of the South and North office buildings during working hours on weekdays,Valve in the middle dormitory buildingclose; On weekends and after work hours, the valves in the south and north buildings are closed, and the valves in the middle building are fully open. By reallocating the cooling supply flow based on changes in cooling demand, the system's power consumption can be effectively reduced.

Implement time and temperature control strategies for fan coil units, and set daily8point-22Point to the panel operation opening period, set the temperature lock to26℃. Commands that exceed the allowed range will not be executed.

Through artificial intelligence optimization measures for cold and heat sources and effective control of end of pipe waste behavior, a significant reduction in system electricity consumption has been achieved.

The platform measures actual energy savings through three different accounting methods

The first one is based onGB/T 28750-2012《General rules for energy-saving measurement and verification technology》The verification method is the direct comparison method.

The second method is to compare and calculate based on the outdoor average enthalpy values that are close to each other.

The third method is to calculate the energy saving rate based on the energy efficiency improvement rate of those with similar daily cooling capacity.

The overall power saving rate is30%Can save daily electricity consumption760kWhRunning for about a year can recoup costs.

Ankerui's HVAC solutions can cover types of air conditioning systems such as split air conditioning, central air conditioning, and multi split systems, effectively helping users achieve energy-saving and cost reduction in their air conditioning systems.
