Overcoming Transportation Constraints, Standardized Custom Modularization Solves Energy-Saving Challenges

Abstract

McDonald's Hong Kong initiated an energy-saving retrofit for its aging main refrigeration units. Conventional compressor condensing units could not be transported to the site due to the dimensional limitations of building elevators. Guangdong Ouyah Refrigeration tailor-made a standardized custom model, splitting the compressor condensing unit into three major modules, easily adapting to elevator transport and efficiently completing the energy-saving upgrade of the refrigeration equipment.

Project Preface

For a global restaurant chain brand like McDonald's, the stable operation of the refrigeration system is the core foundation for ensuring food freshness and normal store operations. As the core host of the refrigeration system, the performance and energy consumption of the compressor condensing unit directly determine the overall cooling effect and operational costs.

Some McDonald's stores in Hong Kong urgently needed an energy-saving retrofit and optimization of their core compressor condensing units due to severe aging, high energy consumption, and declining operational stability of the original refrigeration hosts. However, a critical bottleneck was encountered during the project: the elevator space in Hong Kong commercial buildings is notoriously tight. Conventional standard compressor condensing units are too large to be transported via elevators to the designated installation floors, making universal models completely incompatible with site requirements.

To address this practical challenge, Guangdong Ouyah Refrigeration Equipment Manufacturing Co., Ltd. undertook this customized retrofit task, focusing on the compressor condensing unit itself to create a standardized, custom modular product, successfully overcoming the transportation difficulties and completing the project delivery.

II. Project Background: Core Retrofit Requirements and Rigid Site Constraints

1. Aging Compressor Condensing Units in Urgent Need of Energy-Saving Upgrades

The original compressor condensing units in the affected McDonald's stores in Hong Kong had been in service for a long time. Equipment aging became a major operational pain point:

• On one hand, the outdated technology of the core components led to low cooling efficiency, resulting in persistently high refrigeration-related energy consumption and significantly increasing daily operational costs.

• On the other hand, the old units experienced frequent operational failures. This not only incurred high maintenance frequencies and costs but also posed food safety risks due to potential breakdowns affecting food refrigeration and preservation.

• Furthermore, they could no longer meet Hong Kong's current energy-saving and environmental regulations for commercial equipment, making the retrofit imminent.

2. Limited Elevator Dimensions Prevent Conventional Models from Entering the Site

The core obstacle of this retrofit was not the performance matching of the compressor condensing unit, but the rigid physical constraints of elevator spaces in older commercial buildings in Hong Kong.

• There are strict specifications for the internal height and width of the elevators in the buildings.

• The overall volume and external dimensions of standard-sized compressor condensing units on the market far exceed the load-bearing space of the elevator cars.

• Whether transported as a whole or partially disassembled, they could not smoothly enter the elevators, let alone be transported to the equipment installation area of the store.

Conventional standardized compressor condensing units completely lacked the conditions for on-site implementation, necessitating an exclusive customized design for this core unit.

III. Customized Solution: Standardized Customization + Three-Stage Modular Compressor Condensing Unit

As a professional refrigeration equipment manufacturing enterprise, we always adhere to prioritizing the actual needs of our customers. This project clearly specified that we were only responsible for the custom production and retrofit of the compressor condensing unit. Addressing the elevator transport restrictions and energy-saving requirements, we developed an exclusive solution, optimizing the design solely around the compressor condensing unit without involving other refrigeration accessory components.

1. On-Site Survey for Precise Adaptation through Standardized Customization

Our team of professional engineers immediately visited the affected McDonald's stores in Hong Kong to conduct a comprehensive on-site survey. We accurately measured core parameters such as the length, width, and height of the elevator cars, the equipment installation space, and the store's cooling load requirements.

Strictly adhering to McDonald's quality standards and performance requirements for commercial refrigeration equipment, we carried out a standardized custom design for the compressor condensing unit. This ensured that the core cooling and energy-saving performance of the unit met industry standards and customer needs while fully adapting to the site's transportation and installation conditions in terms of dimensions and structure, achieving a perfect combination of customization and standardization.

2. Core Innovation: Splitting the Compressor Condensing Unit into Three Major Modules

To solve the problem of conventional compressor condensing units being un-transportable, we abandoned the traditional all-in-one integrated design. Without compromising the core performance and operational stability of the unit, we innovatively and scientifically divided the customized compressor condensing unit into three independent, smaller modules. The dimensions and weight of each module were precisely calculated to fully comply with the spatial load-bearing requirements of the elevator, completely resolving the transportation dilemma.

The core advantages of this modular design are highly prominent:

• First, the individual modules are compact and lightweight, requiring no large lifting equipment. They can be easily handled manually and smoothly moved in and out of the elevator cars, perfectly adapting to the narrow transport passages of Hong Kong buildings.

• Second, the modules feature a standardized docking design, making on-site assembly and installation simple and convenient without complex construction, thereby significantly shortening the installation period and minimizing the impact on the store's normal business operations.

• Finally, the modular structure makes subsequent maintenance more convenient; if a single module requires inspection or replacement, there is no need to dismantle the entire machine, lowering future O&M costs and difficulties.

3. Energy-Saving Optimization to Meet Core Retrofit Goals

This customized compressor condensing unit not only solved the transportation problem but also accommodated McDonald's energy-saving retrofit needs. The unit is equipped with highly efficient, energy-saving core components and utilizes an optimized refrigeration system design. Compared to the original old units:

• Cooling efficiency is significantly improved

• Energy consumption is drastically reduced

• Operating noise is lower

• Temperature control is more stable

It fully meets the refrigeration and preservation requirements of chain restaurant stores and helps McDonald's Hong Kong achieve its core retrofit goals of energy conservation, emission reduction, and lower operational costs.

IV. Project Implementation and Practical Results

Smooth Overall Process Without Transportation or Installation Obstacles

During project implementation, we first completed the standardized production, pre-assembly, and performance testing of the three major modules in the factory to ensure that each module met quality standards and performed stably. Subsequently, the three modules were individually packaged. They sequentially passed through the dimensional constraints of the store's elevator transport without any sizing obstacles throughout the process, making the handling efficient and convenient. The equipment successfully passed the client's acceptance inspection and was shipped simultaneously.
