In heating applications, the gas ejector is used in warm and hot climates for generating heat or for reheating. A gas ejector is often located in the exhaust of a heat source such as a furnace or in a thermal store.
Ejectors are used in air conditioning and refrigeration systems for cooling, heating, and dehumidification. In air conditioning and refrigeration systems, the gas ejector is used for improving the cooling of refrigeration systems. This refrigerant is passed from an evaporator to the gas ejector, where it is superheated before being sent to a condenser. The heat released by the superheating of the refrigerant is transferred to a secondary fluid that is used to heat a heat source or to heat a cold space.
The gas ejector is an efficient and compact tool in the process of refrigeration and air-conditioning, and is ideally suited to applications where a large volume of cooling liquid needs to be conveyed at high temperatures and pressures. The gas ejector is used in a wide range of applications including packaging, food and beverage, biotech, pharmaceutical, chemicals, nuclear, biogas, and also in oil and gas.In the civil construction sector, gas ejectors are used for air conditioning and refrigeration systems in both cold and hot climates.
The gas ejector is widely used in process cooling applications, especially in cryogenic process cooling. They are very efficient and compact, and are ideal for applications where a large volume of cooling liquid needs to be conveyed at high temperatures and pressures.
Since the chemical and biological industries have been facing the increasing requirements for biosecurity measures, the use of gas ejectors has increased as reliable, cost-effective, and easy-to-use tools for the removal of air from enclosed spaces.
Ejector outlet temperature is an important parameter of ejectors. Normally steam ejectors are designed to maintain steam temperature close to 500F. A lower steam temperature results in less energy produced and efficiency of the ejector. An ejector operates only when the temperature at the steam nozzle is higher than the design outlet temperature. Ejectors are designed for a motive steam pressure that is not more than the design outlet steam pressure. 827ec27edc
