Conduction oil roof radiation heating system with fresh air preheating function

Abstract

The invention relates to the technical field of heating supply and discloses a conduction oil roof radiation heating system with a fresh air preheating function. The conduction oil roof radiation heating system comprises a conduction oil furnace, an oil pump, a plurality of conduction oil radiation plates, a plurality of control valves and conduction oil pipelines. The oil pump is installed on the conduction oil furnace. The multiple control valves are distributed on the conduction oil pipelines. The conduction oil pipelines penetrate through the multiple conduction oil radiation plates and the conduction oil furnace to form a loop. The conduction oil roof radiation heating system further comprises a fresh air preheating system which comprises a plurality of flat air ducts, air pipes and a positive-pressure fan. According to the heating system, the high-temperature characteristics of conduction oil are sufficiently utilized, and the defect that hot water radiation plates are installed at a high altitude in a high plant is overcome; and meanwhile, fresh air is preheated through the temperature of the conduction oil radiation plates, loads of cold air infiltration to heating can be effectively relieved during heating, and the conduction oil roof radiation heating system is economical and capable of saving energy.

Description

Technical field [0001] The invention relates to the technical field of heating and heating, in particular to a thermal oil ceiling radiant heating system with fresh air preheating function. Background technique [0002] At present, most common heating systems are hot water systems, but the hot water pipe network has a large heat loss during the transportation process. Especially in severe cold areas such as the Northeast, pipeline freezing and cracking often occur in winter, which has a large or small impact on production and life. At the same time, the hot water boiler is a pressure equipment, which is inherently dangerous and requires special personnel to manage and maintain it on a regular basis. The operating cost is relatively high. In actual engineering, problems caused by poor management often occur. [0003] For the heating of tall factories, traditional radiator heating basically cannot meet the comfort requirements. Hot air heating overcomes the shortcomings of the radi...
