An evaporative cooler (also known as evaporative air conditioner, swamp cooler, swamp box, desert cooler and wet air cooler) is a device that cools air through the evaporation of water. Evaporative cooling differs from other air conditioning systems, which use vapor-compression or absorption refrigeration cycles.

In this system, the engine-cooling water is passed through a heat exchange, where it is cooled by concentrated seawater. Because the cooling water, which is chemically treated fresh water, is at a temperature of 70–80 °C (158–176 °F), it would not be possible to flash off any water vapor unless the pressure in the heat exchanger vessel is ...
A heat recovery system helps keep a house ventilated while recovering heat being emitted from the inside environment. The purpose of heat recovery systems is to transfer the thermal energy from one fluid to another fluid, from one fluid to a solid, or from a solid surface to a fluid at different temperatures and in thermal contact.
Passive cooling covers all natural processes and techniques of heat dissipation and modulation without the use of energy. [1] Some authors consider that minor and simple mechanical systems (e.g. pumps and economizers) can be integrated in passive cooling techniques, as long they are used to enhance the effectiveness of the natural cooling process.

Installing a water heat recycler reduces energy consumption and thus greenhouse gas emissions and the overall energy dependency of the household. Typical retail price for a domestic drain water heat recovery unit ranges from around $400 to $1,000 Canadian. For a regular household, water heating is usually about 20% of overall energy demand.
South Africa won a bilateral Twenty20 series for the first time in more than two years when it chased down Pakistan's 206 on Friday. Opener Reeza Hendricks' maiden T20 century, 117 off 63 balls ...
A heating coil is the part of the system that conducts heat. It allows electricity to act as fire. heat exchanger A heat exchanger is the part of the system that transfers heat from the hot parts of the machine or a system to the cold parts of the machine or system. heat gain heat load heat loss
