Passive cooling. A traditional Iranian solar cooling design using a wind tower. Passive cooling is a building design approach that focuses on heat gain control and heat dissipation in a building in order to improve the indoor thermal comfort with low or no energy consumption. [1] [2] This approach works either by preventing heat from entering ...
Free cooling is an economical method of using low external air temperatures to assist in chilling water, which can then be used for industrial processes, or air conditioning systems. The chilled water can either be used immediately or be stored for the short- or long-term. When outdoor temperatures are lower relative to indoor temperatures ...
An air cycle machine ( ACM) is the refrigeration unit of the environmental control system (ECS) used in pressurized gas turbine -powered aircraft. Normally an aircraft has two or three of these ACM. Each ACM and its components are often referred as an air conditioning pack. The air cycle cooling process uses air instead of a phase changing ...
The Metro Action Commission is hoping to help. Through the Summer Cooling Program, eligible residents can receive a free fan or air conditioning unit and, in some circumstances, both, between now ...
Insulated shipping container. Insulated shipping containers are a type of packaging used to ship temperature sensitive products such as foods, pharmaceuticals, organs, blood, biologic materials, vaccines [1] and chemicals. They are used as part of a cold chain to help maintain product freshness and efficacy. The term can also refer to insulated ...
June 20, 2024 at 5:32 PM. By Amina Niasse. NEW YORK (Reuters) - UnitedHealth Group issued a public notice about the February ransomware hack on its Change Healthcare unit on Thursday as part of ...
Radiative cooling. Earth's longwave thermal radiation intensity, from clouds, atmosphere and surface. In the study of heat transfer, radiative cooling [1] [2] is the process by which a body loses heat by thermal radiation. As Planck's law describes, every physical body spontaneously and continuously emits electromagnetic radiation .
Moisture vapor transmission rate ( MVTR ), also water vapor transmission rate ( WVTR ), is a measure of the passage of water vapor through a substance. It is a measure of the permeability for vapor barriers . There are many industries where moisture control is critical. Moisture sensitive foods and pharmaceuticals are put in packaging with ...
