An air heat exchanger is a device that is used to transfer heat between two air streams. It is commonly used in heating, ventilation, and air conditioning (HVAC) systems. The heat exchanger can be designed to allow the two air streams to be either separately or together.
Generally, we classify the air heat exchanger into Finned Tube Heat Exchanger, Plate Type Air Heat Exchanger, Seamless Pipe Air Heat Exchanger, Twisted Heat Exchanger, etc. according to its structure.
Air heat exchangers are commonly used for a variety of applications in the HVAC system, such as space heating, cooling, humidification and air circulation. In space heating applications, air heat exchangers are used to transfer heat from outside air to indoor air, in order to provide heat for the building. In cooling and air circulation applications, air heat exchangers are used to transfer heat from an indoor space to the outside. in order to keep the building cool.
The main advantage of using an air heat exchanger is that it is very efficient in transferring heat energy between the two streams without any loss. It is also relatively inexpensive, compared to other types of heat exchangers. Additionally, air heat exchangers are small and compact, making them ideal for applications in tight spaces.

Recently, it was learned from the science and technology department of Zhaoqing City, Guangdong Province that in order to speed up the promotion and application of LED products and promote energy conservation and emission reduction, Zhaoqing City recently issued the “Implementation Plan for Promoting the Use of LED Lighting Products†(hereinafter referred to as “Programâ€). Before the end of 2013, Zhaoqing The city's public lighting sector will complete the promotion and application of 80,000 LED lights.
According to the "Program", Zhaoqing City strives to popularize LED lighting in the field of public lighting for two years, and is the first to complete the use of LED lighting products in the field of lighting engineering such as roads, public places and government agencies.
The "Program" also clearly guides the goal of promoting the application of LED lighting products in rural areas. That is to say, according to the actual needs of the rural areas, demonstration projects in rural areas will be implemented in central villages and key villages to guide the application of lighting products to rural areas.
It is reported that in addition to the light effect is very good, LED lights also have obvious advantages in energy saving, LED lights can reach 50% than ordinary high-pressure sodium lamps. It is worth mentioning that the LED lamp uses a central energy-saving system with controllable and adjustable functions. The street lamp is around 3 or 4 in the morning, and there are few passers-by. Its power will be automatically adjusted downwards, so that it is based on energy saving. More energy efficient. LED lamp life is about 3 years longer than the street lamp currently in common use, and can generally reach a service life of 5 years.
