[8] [13] SPX’s headquarters relocated to Charlotte, North Carolina, in 2002. [8] In 2012, SPX president Charles E Johnson II sold its Service Solutions business for approximately $1.15 billion to Robert Bosch GmbH. [14] [15] [16] In 2015, SPX Flow was founded, a spin-off from its parent company. [17]
Bleed air from the engines, an auxiliary power unit, or a ground source, which can be in excess of 150 °C and at a pressure of perhaps 32 psi (220 kPa), [1] is directed into a primary heat exchanger. Outside air at ambient temperature and pressure is used as the coolant in this air-to-air heat exchanger.
The operations manual is the documentation by which an organisation provides guidance for members and employees to perform their functions correctly and reasonably efficiently. [1] It documents the approved standard procedures for performing operations safely to produce goods and provide services. [ 2 ]

Figure 1: Schematic drawing of a Stirling-type single-orifice PTR. From left to right: a compressor, a heat exchanger (X 1), a regenerator, a heat exchanger (X 2), a tube (often called the pulse tube), a heat exchanger (X 3), a flow resistance (orifice), and a buffer volume. The cooling is generated at the low temperature T L. Room temperature ...

In the Faroe Islands, wild, unpredictable weather — fierce winds and rain, and thick fog that settles like a curtain — can sometimes make travel by car or ferry problematic.
SoundEnergy developed the THEAC system that turns heat, typically waste heat or solar heat into cooling with no other power source. The device uses argon gas. The device amplifies sound created by the waste heat, converts the resulting pressure back into another heat differential and uses a Stirling cycle to produce the cooling effect. [2]
