Project Overview

Maintaining stable temperature and humidity is essential for cool storehouses, where fluctuations in environmental conditions can affect product quality, storage stability, and operational efficiency. In Malaysia’s warm and humid climate, HVAC systems for temperature-controlled storage must provide reliable cooling while maintaining precise humidity conditions under varying outdoor loads.

For a cool storehouse project in Malaysia, VENTTK supplied a Packaged Rooftop Unit designed for constant temperature and constant humidity control. With an integrated system configuration and intelligent control architecture, the unit provides coordinated cooling, heating, humidification, and air-conditioning functions to establish a stable indoor environment for temperature-sensitive storage applications.

Project Features

The system integrates multiple environmental control functions into one packaged HVAC solution, reducing the complexity associated with installing and coordinating separate equipment. Its integrated configuration is particularly suitable for applications requiring continuous and stable indoor environmental conditions.

The 22 kW cooling capacity provides effective heat removal for the cool storehouse, while the 82 kW electric heating capacity enables the system to compensate for low-temperature conditions and maintain the required indoor setpoint. With a 6 kg/h humidifying capacity, the unit can also regulate indoor moisture levels, helping maintain a controlled temperature-humidity environment.

The refrigeration system uses R410A refrigerant, while the Copeland compressor provides a reliable core component for continuous refrigeration operation. The Siemens control system enables centralized monitoring and intelligent regulation of key operating parameters, supporting stable system performance and convenient operation.

The packaged rooftop configuration also offers advantages in equipment integration, installation efficiency, space utilization, and centralized system management. The solution can be adapted to the specific environmental and operational requirements of the storage facility.

Project Significance

This project demonstrates the importance of integrated temperature and humidity management in cool-storehouse applications in tropical regions. For Malaysia, where high ambient temperatures and humidity can place additional demands on HVAC systems, a reliable constant temperature and constant humidity solution helps create a more stable indoor storage environment.

By combining cooling, electric heating, humidification, refrigeration, and intelligent control within one integrated system, we provide a practical HVAC solution for controlled-storage applications. The project also reflects VENTTK’s capability to develop and supply customized environmental control equipment for overseas customers with different climate conditions and application requirements.
