Question

Give one example to explain how thermal insulation plays an important role in the following areas:

(a) Space suit
(b) Dairy industry
(c) Air conditioning in office buildings
(d) Refrigeration
​

Answer 1

Answer:

The insulation materials studied include polyurethane (PU) foam and vacuum insulation panels (VIPs) made with fumed silica, glass fibre and alternative core materials. ... Glass fibre VIP insulated refrigerator was found to have no payback because of their increased thermal conductivity due to ageing.

A space suit or spacesuit is a garment worn to keep a human alive in the harsh environment of outer space, vacuum and temperature extremes.

Answer 2

ANSWER:

• Thermal insulation in space suit means have been subjected to preliminary evaluation by NASA to attempt to identify a material that will meet the target conductivity of 0.005 W/m-K!
• Thermal insulation is used in dairy and food industries to prevent heat loss or heat gain. Such materials are porous, containing large number of air cells!
• A case study on thermal insulation in air conditioning was performed in Turkey.It revealed that the sir conditioning by thermal insulation adapted to the climatic conditions so perfectly and accurately.
• Thermal insulation performs a vital role in limiting heat gains in an industrial refrigeration system, ensuring that the compressor load does not become excessive. ... Insulation is also used to conserve energy, prevent condensation or ice formation and minimize corrosion.
