Hot air behind your cold fridge? Why the future of cooling must be sustainable

Picture this: you live in a hot and humid climate, and you get access to energy. What’s the first thing you buy to stay cool? An air conditioner (AC). As incomes and standards of living increase around the world, so does the use of ACs. As a result, the global energy demand for ACs is  expected to triple by 2050 . However, people are buying units with average efficiencies of less than half of what is available on the market. To respond to the growing demand for cooling, we must, first and foremost, think energy efficiency. Cooling appliances such as ACs consume energy and emit heat while running. Anyone who has ever put their hand behind their fridge knows what I’m talking about. In turn, these heat gains add to air-conditioning demand. This dynamic, combined with the rising demand for cooling, drives up both power needs and CO2 emissions. Hence the need to think energy efficiency. Sustainable cooling solutions I am fiercely passionate about supporting the d...

VCI plastic bags

VCI Plastic Bags for safe packaging Safepack  VCI Plastic Bags  are designed for packaging cargo goods and products to ensure long life and protection from corrosion.   KEY FEATURES Best in class protection against moisture, oxygen transmission, corrosion, physical damage, odour transfer Corrosion is kept at bay by maintaining humidity level below 40 RH. Overall cost reduction by way of reduced desiccant/preservatives, packing case cost and rejections due to corrosion and spoilage of packed products   How do VCI Bags Work?   VCI bags , or Vapor Corrosion Inhibitor bags emits molecules that settle on metal surface result is a thin protection layer collect which is act as Corrosion Inhibitor. It protects by interrupting the electro-chemical corrosion process caused by moisture, oxygen and contaminants in the atmosphere.

External vs internal gears

An external gear is one with the teeth formed on the outer surface of a cylinder or cone. Conversely, an internal gear is one with the teeth formed on the inner surface of a cylinder or cone. For bevel gears , an internal gear is one with the pitch angle exceeding 90 degrees. Internal gears do not cause output shaft direction reversal
