3. BACKGROUND OF THE STUDY
• Ice cream is a perishable product that has been a favorite dessert for centuries. But its storage
requires specific environmental conditions, primarily controlled temperature, and humidity, to
maintain quality and avoid spoilage.
• Cold storage facilities offer an environment that can be adapted to satisfy the specific needs of
various products.
• Humidity management is an important aspect of ice cream preservation. Inadequate humidity
levels may result in issues such as ice recrystallization and freezer burn.
• Johnson (2019) investigated different humidity control systems for ice cream storage facilities.
• The design and optimization of the storage environment, specifically the ventilation system,
significantly impacts the preservation of ice cream.
4. STATEMENT OF THE PROBLEM
1. What cooling load is required to maintain the desired
temperature of -18C to -30C for preserving ice cream?
2. What is the ideal facility size for the cold storage to fill in
5000 liters of ice cream?
3. What ventilation system design is best for minimizing the
heat load from room surfaces?
4. How many sensors are necessary to monitor and regulate
the temperature and humidity levels within the cold storage
facility?

6. SCOPE AND DELIMITATIONS
The researcher aims to create an improved ventilation
system design, particularly for an ice cream preservation
focused cold storage facility with a daily capacity of 5000
liters. This includes calculating ventilation requirements
based on facility size and ice cream volume. Furthermore,
this study covers ducting design and pipework of storage.
8. Cold Storage Facility. Cold storage facility involves the storing of perishable or other sensitive goods like food at a
specific temperature range to maintain their integrity, shelf-life, and quality (Conger Industries Inc., 2022).
Cooling Load. The cooling load is the quantity of heat energy that must be added to an area in order to keep the
temperature within a reasonable range (New South Whales, 2023).
Heat Transfer. Any time there is a temperature difference between two items, heat transfer happens. It also happens
in the direction of decreasing temperature, that means from a hot object to a cold object (Access Science, 2023).
Humidity. Water vapor content in the air is referred to as humidity. Humidity levels will be high if there is a lot of water
vapor present. It feels wetter outside when the humidity is higher (National Geographic, 2023).
Preservation. It can be defined as the process of treating and handling food in such a way as to stop or greatly slow
down spoilage and prevent foodborne illness while maintaining nutritional value, texture and flavor (ScienceDirect, 2023).
Ventilation System. A comprehensive system of ventilation is essential to effective HVAC. Ventilation is a separate
mechanism from heating or air conditioning but works in conjunction with both, maintaining the airflow necessary to
effectively heat or cool a building (Data Center, 2021).
