Heat exchanger and air conditioning system adopting same

Abstract

The invention relates to the technical field of air conditioning equipment, in particular to a heat exchanger and an air conditioning system adopting the same. The heat exchanger comprises a refrigerant heat exchange side and a medium heat exchange side; the refrigerant heat exchange side and / or the medium heat exchange side are / is made of a corrosion-resistant material, and a welding seam for connecting the refrigerant heat exchange side and / or the medium heat exchange side is welded through a welding flux of the corrosion-resistant material. A water chilling unit, a water source heat pump unit, a sewage source heat pump unit, a seawater source heat pump unit, an air source heat pump unit, an energy tower heat pump unit and an air conditioning system which adapts to any water sources such as acid, alkali and salt in the chemical industry field can be manufactured; the service life of the air conditioning system is greatly prolonged by several times compared with that of an existing air conditioning unit, and the social benefit is great; according to the assembly type universal air conditioner room, a large number of peasant workers can be saved for field installation, the pressure of difficulty in recruitment in China at present is relieved, and the problem of aging society in China can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of air-conditioning equipment, in particular to a heat exchanger and an air-conditioning system using the heat exchanger. Background technique [0002] Air conditioners have been widely used in all walks of life and family life, and there are various types of air conditioners, but there is no universal air conditioner suitable for any air conditioning system application. Especially for water-cooled air-conditioning units, under the current situation of increasingly serious environmental pollution, general air-conditioning units are easily corroded. As we all know, the compressor of the air-conditioning unit can run normally for more than 20 years without failure, but the heat exchanger will be scrapped after seven or eight years at most, and the service life rarely exceeds ten years. [0003] Sewage source heat pumps are increasingly widely used, especially oily sewage reserves in oil fields are huge, and t...

Problems solved by technology

However, titanium alloy tubes have excellent seawater resistance, but they are expensive, and the application cost is high and it is difficult to promote them in a large area.

[0004] Brazed plate heat exchangers currently have plate heat exchangers made of stainless steel 304 and stainless steel 316, but for seawater and sea salt antifreeze, the brazed plate heat exchangers made of 304 and 316 stainless steel cannot withstand its corrosion

Since the brazed plate heat exchanger uses brass as the welding material, the brass welding part is easily cracked after being corroded, resulting in the failure and scrapping of the brazed plate heat exchanger
