Project Overview
In 2022, LINUO RITTER deployed 30 sets of 150kW commercial air source heat pump systems for a large school covering 80,000 square meters in a province of Vietnam, achieving year-round comfortable environmental control with summer cooling and winter heating. The system, through fan coil units, provides 55โ hot water to maintain a room temperature of 22โ in winter and maintains a room temperature of 26โ in summer, creating a healthy, energy-efficient, and comfortable learning environment for teachers and students.
Core Problems Solved
I.Vietnam experiences hot and humid summers and cold, damp winters in the north.
Traditional air conditioning only provides cooling and cannot meet the heating needs in winter. LINUO RITTER air source heat pump integrated cooling and heating units achieve “dual-purpose” functionality, providing efficient cooling and dehumidification in summer and stable heating in winter, ensuring comfortable temperatures in classrooms, offices, dormitories, and other areas throughout the year, improving teaching quality and teacher and student satisfaction.
- High Energy Consumption and Operating Costs of Large Public Buildings
Traditional split-type or central air conditioning systems for an 80,000 square meter campus consume enormous amounts of energy, with electricity costs accounting for a high proportion of operating costs. The heat pump system utilizes air heat energy, and its energy efficiency is more than 3 times higher than that of traditional electric air conditioners. The intelligent zoning control automatically adjusts according to the classroom usage time and number of people, avoiding energy waste during unattended periods. It is expected to save 40-50% of air conditioning electricity costs, significantly reducing the school’s operational burden.
III. Quiet Campus Environment and Air Quality Requirements
Schools require a quiet teaching environment and healthy indoor air quality. The heat pump unit is centrally located in the equipment room, away from classrooms, resulting in low operating noise. The water system circulates CFC-free water directly into the rooms, working in conjunction with a fresh air system to avoid the direct blast of air and dryness associated with traditional air conditioning, reducing the spread of respiratory diseases and protecting the health of teachers and students.
Customer Feedback
The school is very satisfied with the system’s performance, stating that the warmer classroom environment in winter and cooler in summer significantly improves student concentration and teacher productivity; electricity costs have decreased substantially, and the payback period meets expectations; the equipment operates stably, is easy to maintain, and has a low failure rate. This project demonstrates the advantages of commercial heat pumps in large public buildings.
With its efficient and reliable commercial heat pump solutions, LINUO RITTER has successfully provided Vietnamese schools with year-round comfortable, economical, energy-saving, healthy, and environmentally friendly environmental control solutions, contributing to the sustainable development of educational infrastructure in Southeast Asia.
