FAQ

MEP Engineering FAQ

Common questions regarding AC energy saving and MEP retrofitting

How long does a typical AC energy-saving retrofit take?

It depends on factory scale. A mid-sized factory typically takes 2-4 months from assessment to completion. We use zone-based construction to ensure production is not disrupted.

What is the ESCO (Energy Service Company) performance guarantee model?

Under the ESCO model, Shi-He Intelligent handles design, construction, and acceptance while guaranteeing energy savings. Enterprises pay with the money saved on electricity, reducing upfront investment pressure, with typical payback in 2-3 years.

What is the actual energy-saving guarantee ratio of the ESCO model?

Depending on the equipment status and site requirements, the energy-saving ratio typically falls between 20% and 40%. ShiHe Intelligent signs an "Energy Performance Guaranty (EPC) Contract." If the target is not met, we compensate for the difference, ensuring zero-risk energy saving with no upfront capital expenditure.

What is the technical principle of the Nano-Ice Crystal Cold Storage system?

It uses off-peak electricity (low tariff periods) to store cooling energy in nano-materials with high phase-change latent heat, releasing it during peak periods (high tariff periods) to reduce the chiller load. This achieves "peak shaving and valley filling," significantly optimizing basic electricity bills and energy costs.

Will the retrofitting affect factory production during construction?

We use "non-stop construction" or "phased switching" strategies. Before engineering, we communicate deeply with the factory to avoid peak production periods or concentrate construction during annual maintenance shutdowns, with emergency power and AC backup plans to ensure production line stability.

Generally, what is the ROI for MEP energy-saving projects?

Depending on system complexity, the average payback period is about 2 to 4 years. If "dual-effect heat pumps" are used to resolve both AC and hot water needs simultaneously, or if waste heat is recovered for reuse, the payback period can even be shortened to within 1.5 years.

Which industries are most suitable for these MEP energy-saving technologies?

Semiconductor plants and food/pharmaceutical factories requiring 24-hour constant temperature and humidity, as well as hotels, hospitals, and textile dyeing industries with high hot water demand, can all gain extremely high marginal benefits from AC optimization and waste heat recovery.

Will maintenance costs increase after the retrofit?

No, they will actually decrease significantly. Through EMS smart monitoring and "predictive maintenance," expensive repairs from sudden failures are reduced. Newer equipment is more reliable, typically lowering long-term O&M costs by 15-20% compared to traditional old systems.
