Multiple-unit solar water heating equipment

Abstract

The invention relates to multiple-unit solar water heating equipment, which uses a plurality of serially connected and parallelly connected solar heating stoves for heating heat conducting oil, wherein the heated heat conducting oil is used for heating cold water and increasing the temperature of the cold water for production and life through a heat conducting oil radiating pipe by means of pumping circulation of a gear pump. The specific scheme includes that a plurality of solar stoves capable of automatically tracking, focusing and collecting solar energy are serially connected and parallelly connected, and the heat conducting oil serves as heat transfer media. Each heat absorption stove is provided with a multi-pass circular coil pipe, and one gear oil pump is used for oil pumping circulation. An oil inlet pipe and an oil outlet pipe of each heat absorption stove are connected with an outer oil transport pipe through hoses, and a regulating valve is mounted at an outlet of the gear oil pump and can be used for regulating flow. The oil inlet pipe of each solar stove is provided with a regulating valve capable of regulating flow, and more solar stoves are parallelly connected if high heat and temperature are needed. The heated heat conducting oil is used for heating the water in a cold water tank through a pipeline and the radiating pipe, the cold oil after radiating flows into a high-level oil seal barrel, partial air or oil can be discharged through an exhaust valve on the upper portion of the barrel, and return oil enters the gear oil pump again, is pumped to a system, and is reheated for use.

Description

technical field [0001] The invention relates to a hot water device, which is a hot water device that utilizes the heat concentrated by multiple groups of solar energy to circulate and heat. technical background [0002] There are many kinds of hot water equipment in the society at present, basically adopt solar energy to heat water or use electricity to heat etc., at the bottom of northern winter temperature, outdoor below zero, water all freezes. In winter, the sunlight is short and the intensity is relatively weak. Directly absorbing sunlight to heat cold water is not ideal. In order to prevent the water in the solar water heater from freezing in the evening and going bad in winter, electric heating is often used to maintain heat preservation, which will consume a large amount of electric energy again. The invention adopts multiple sets of solar heating stoves to be connected in series and in parallel, heat conduction oil is used as the heat transfer medium, and the high ...

Problems solved by technology

In winter, the sunlight is short and the intensity is relatively weak. Directly absorb sunlight to heat cold water, and the effect is not ideal.

In order to prevent the water in the solar water heater from freezing at night and spoiling in winter, electric heating is often used to maintain heat preservation, which consumes a lot of electric energy
