Method for mounting coolant pipes of air conditioning system

Abstract

The invention belongs to the field of the construction of civil architectures, and in particular relates to a method for mounting coolant pipes of an air conditioning system, which comprises: a first step of making preparations for the construction; a second step of machining copper pipes; a third step of braze-welding and connecting the copper pipes; a fourth step of laying the copper pipes; a fifth step of washing the copper pipes; a sixth step of performing airtight test; a seventh step of realizing the temperature preservation of a pipeline; an eighth step of vacuum-drying the pipeline system; a ninth step of supplementing a coolant; and a tenth step of performing pre-operation. In the invention, the copper pipes have the characteristics of bacteria growth inhibition, corrosion resistance, durability and long service life; and the method has the advantages of capacity of effectively improving a construction progress, relatively shorter construction period, and simple operation andconvenient maintenance because only a tube flaring kit, a pipe expander and a cutter are needed when the copper pipes are maintained, meets national requirements on energy-saving engineering and is favorable for promoting the research, development, integration and large-scale application of matching technology combining renewable energy sources and the architectures.

Description

Technical field: [0001] The invention belongs to the field of civil building construction, and in particular relates to a method for installing a refrigerant pipe of an air-conditioning system. Background technique: [0002] Traditional air-conditioning systems use galvanized steel pipes as refrigerant pipes. The chemical properties of the refrigerant pipes are insufficient in inhibiting bacterial growth. The service life of galvanized steel pipes is very short, the thermal conductivity is relatively poor, and the thickness of the pipes is relatively thin. The inner wall is also prone to rust and scaling. The weight of galvanized steel pipe is relatively large, so it brings great inconvenience to the construction, seriously affects the speed of construction, and increases the construction period. In addition, in terms of energy saving and environmental protection, the chlorine contained in the traditional refrigerant R22 will destroy the ozone layer, and there are great hid...

Problems solved by technology

[0002] Traditional air-conditioning systems use galvanized steel pipes as refrigerant pipes. The chemical properties of the refrigerant pipes are insufficient in inhibiting bacterial growth. The service life of galvanized steel pipes is very short, the thermal conductivity is relatively poor, and the thickness of the pipes is relatively thin. The inner wall is also prone to rust and scaling

The galvanized steel pipe is heavy, so it brings great inconvenience to the construction, seriously affects the speed of construction, and increases the construction period

In addition, in terms of energy saving and environmental protection, the chlorine contained in the traditional refrigerant R22 will destroy the ozone layer, and there are great hidden dangers in energy saving and environmental protection. In today's society that pays attention to environmental protection, the market prospect of this product is not optimistic, and the market share will increase. lower
