Oil-water classified type solar heating system and method suitable for swimming pool

Abstract

The invention discloses an oil-water classified type solar heating system and method suitable for a swimming pool. The system comprises a solar heat collecting system, a temperature control system, anoil-water heat exchange system and a circulation pressurizing device. The solar heat collecting system is a CPC light gathering type solar heat collector and comprises three parts including a transparent baffle, a reflection face and a heat collecting pipe, wherein a heat transfer medium is heat conduction oil. The temperature control system comprises a temperature controller, an electric heaterand a temperature sensor. The oil-water heat exchange system is a heating coil pipe at the bottom of the swimming pool, high-temperature heat conduction oil walks in the coil pipe, the double-concentric-square-shaped pipe arranging manner is adopted in the coil pipe, a water inlet and a water outlet pipe of the coil pipe are arranged in a spaced manner, and the bottom temperature uniformity of theswimming pool is guaranteed. According to the method, the heat conduction oil circularly absorbs solar energy in a solar heat collecting field and exchanges heat energy with swimming pool water in the oil-water heat exchange system, the swimming pool water heating task is finished, and the beneficial effects that heat losses are low, and stability is high are achieved.

Description

technical field [0001] The invention belongs to the technical field of solar heating, and relates to a swimming pool heating technology using solar energy, in particular to an oil-water graded solar heating system and method suitable for swimming pools. Background technique [0002] With the rapid development and progress of human beings, the problems of environmental pollution and the imminent depletion of non-renewable energy sources have come to the fore. The use of a large amount of coal and oil produces a large amount of harmful gases such as sulfur dioxide, nitrogen monoxide, carbon monoxide, etc. and a large number of fine particles. At the same time, the extensive use of coal and oil has sharply increased the carbon dioxide content in the air. A large amount of carbon dioxide spread in the air is like covering the earth with a quilt to promote global warming. The original climate and ecological environment have encountered unprecedented impact. Moreover, the energy ...
