Direct heating type air source floor radiation heat supply system construction method

Abstract

The invention relates to a direct heating type air source floor radiation heat supply system construction method. A heat insulating layer is laid on a leveling layer, aluminum foil is laid on the heatinsulating layer to serve as a reflection layer, an embedded capillary coil pipe is laid and fixed, an embedded intake manifold and a liquid return header pipe are laid and fixed, and a heating medium branch device is connected; outer unit equipment installation is conducted, a header pipe and outer unit equipment are connected, system sweeping and dirt discharging are conducted, then, first-timesystem pressure testing is conducted, and leakage is checked and eliminated in the pressure testing process till pressure testing is qualified; and indoor cushion layer construction and second-time air pressure testing are conducted, and total-system pressure testing debugging is conducted after second-time pressure testing is qualified. According to the construction method, the system and outerunit equipment connection method is standardized, and equipment installation and maintenance are convenient. The waterproof measure is taken at the positions of indoor connectors and outdoor connectors, outdoor rainwater is prevented from seeping into the indoor system, copper pipe water immersing and corroding are avoided, safe running of the system is facilitated, and the service life is prolonged. Template trepanning is not needed for strong and weak electricity tubing wiring construction, and template integrity is not damaged.

Description

technical field

[0001] The invention relates to an air source radiation heating system, in particular to a construction method of a direct heating air source floor radiation heating system. Background technique

[0002] The direct heating air source floor radiant heating system is a form in which the heat medium transforms heat through condensation and directly transfers heat to the floor to achieve the purpose of indoor heating. It is a new heating method that is comfortable, energy-saving, simple, safe, Environmentally friendly features. It not only brings a comfortable family environment, but also effectively reduces operating costs. At present, the construction technology of direct heating air source floor radiant heating system has the following problems and defects:

[0003] The construction process is not perfect, and the construction cost is high. The power line and control line simply refer to the multi-line construction method, and are connected to the external ...
