TA balance valve application of technical regulations to promote the seminar held recently

An energy-saving technology and products that can save up to 30% of transmission and distribution energy in the air-conditioning system, Sweden's hydraulic balance valve into Shanghai, Shanghai, competing for the office business applications. City Construction Technology Promotion Center and HVAC Technology Exchange Network jointly held a TA balancing valve application of technical regulations recommended seminars. Experts in the study that the balance valve products used in HVAC water system, with high regulation accuracy, excellent performance characteristics, the rational use of the product to reduce building energy consumption, to create a comfortable indoor environment is of great significance. It is reported that TA balancing valve application of technical regulations by the Urban Construction Standardization Office recommended as the recommended application of building materials in Shanghai standard. Swedish company TA has a history of over one hundred years. In 1962, it invented the world's first hydraulic balance valve and has been leading the world in hydraulic balance for many years. Companies focus on technology, advocated by a comprehensive water balance technology to create air conditioning, hot water supply system for the balance of technology precedent.

Fixed Tube Heat Exchanger

Fixed tube heat exchanger consists of tube bundle, tube plate, shell, head, folded plate, etc. Tube bundle ends fixed in the tube plate, the tube can be expanded (the inner hole of the tube with mechanical expansion, so that the tube wall from the inward to outward extrusion and fixed in the tube plate) or welded to the tube plate. The tube bundle is placed within the tube shell, with headers and flanges fixed at both ends. In this way, one fluid flows from the inside of the tube and the other from the outside. The space between the two heads and the tube plate is used to distribute or collect the fluids inside the tube. The two fluids do not mix with each other, but only exchange heat through the tube wall.

Advantages: simple and compact structure, high pressure resistance, low cost and easy to clean the tube side.

Disadvantages: Risk of blockage when the tube is damaged or needs to be replaced.

When the difference between the wall temperature of the tube bundle and the shell or the coefficient of linear expansion of the material is large, a large thermal stress will be generated in the shell and the tube bundle. A flexible compensation ring (also called expansion joint) should be installed on the shell to reduce the thermal stress.
