Modification And Performance Evaluation Of A Cold Room Storage Structure

3.3    Designed Consideration
    The design consideration for this project was based on the type of the cold storage system, capacity, power requirement and nature of fruits and vegetables to be stored in the cold storage system.
3.3.1    Cold Storage system
    The type of cold storage system used is special (combi) cold storage machinery for fruits and vegetables with other items. These facilities store potatoes and other vegetables at one temperatures and also have other compartment specially designed for keeping seeds, pulps, and fruits at the best temperature for preservation. It has various units for proper control of temperature and relative humidity.
3.3.2    Capacity of the cold storage system
    It is generally defined in terms of the store volume but there are a number of ways in expresses this value. It is measure in cm3.
    Gross volume: is the volume of the refrigerated space.
    Effective volume: is the store space that can actually be utilized for storage and its; takes into account the requirement for passage ways stacking equipment e.t.c
V =     L  x B x H (cm3).
3.3.3    Power Requirement for cold storage system
    The power required for the operation of a cold storage system is high-voltage main electricity. A transformer unit must supply low-voltage mains in the establishment via a general switchboard.
3.3.4    Nature of Fruits and vegetables
    Fresh, filling and heart-healthy, fruits and vegetables are an important part of your overall healthy eating plan.
    They are high in vitamins and minerals that are good for your health. These include vitamins A (beta-carotene), C and E, magnesium, Zinc, phosphorous and folic acid. Folic acid may reduce blood levels of homocysteine, a substance that may be a risk factor for coronary heart disease.
    Eating a variety of fruits and vegetables may help you control your weight and your blood pressure.
