Indoor heating system based on coupling of separated heat pipe and flat-plate solar heat collector

Abstract

The invention discloses an indoor heating system based on coupling of a separated heat pipe and a flat-plate solar heat collector. The indoor heating system comprises an outdoor heat collection component and an indoor control component, wherein the outdoor heat collection component comprises a heat collector box body, a heat absorption plate core, an evaporation heat-exchange pipe and an evaporation chamber; the heat absorption plate core, the evaporation heat-exchange pipe and the evaporation chamber are arranged in the heat collector box body; the indoor control component comprises a hot water storage tank, a spiral pipe type condenser, a liquid accumulating cup, a temperature sensor, a flow control pump, a gas-liquid separator, a cold-heat exchanger, an air intake fan, an air intake fan pipeline, an air exhaust fan and an air exhaust fan pipeline; the spiral pipe type condenser is placed in the hot water storage tank and provided with a flow inlet and a flow outlet; the flow inlet end of the spiral pipe type condenser is connected with an evaporation gas outlet; and the flow outlet of the spiral pipe type condenser is connected with a condensate inlet. The indoor heating system adopts a separated heat pipe technology, ensures high thermal efficiency and meanwhile solves the problem of freezing prevention of the flat-plate solar heat collector and system pipelines.

Description

technical field [0001] The invention belongs to the field of solar energy utilization, and in particular relates to an indoor heating system coupled with a separated heat pipe flat solar heat collector. Background technique [0002] With the development of society, people's material and cultural living standards have been significantly improved. Solar water heaters, as a household heating and heating equipment to improve people's living conditions, have been widely used in both urban and rural areas. Scientists say that knowing new energy sources and using them correctly means knowing the way to the future. At present, the problem of resources and energy is becoming more and more serious. How to effectively and rationally allocate and utilize resources and reduce conventional energy consumption while ensuring comfort and health requirements has become a problem that people have to face; in recent years, the rapid development of the domestic market economy, enterprises, indus...

Problems solved by technology

At present, the problem of resources and energy is becoming more and more serious. How to effectively and rationally allocate and utilize resources and reduce conventional energy consumption while ensuring comfort and health requirements has become a problem that people have to face; in recent years, the rapid development of the domestic market economy, enterprises, industries The product structure is constantly changing, and the market competition is fierce. Affected by the relationship between market supply and demand, China's solar water heater industry has developed rapidly. Today's solar water heaters have huge capacity, mainly flat-plate solar water heaters and vacuum tube solar water heaters; ordinary flat-plate solar water heaters There is no antifreeze function, so it is not suitable for the north; although the vacuum tube type solar water heater is suitable for the north, because the vacuum tube is easy to burst, the maintenance rate is high; in addition, there is a heat pipe flat water heater in the market. It is connected together, which can be applied to both the south and the north, but its structure is complicated and the manufacturing cost is high, so it can only be installed on the roof of a multi-storey building on the roof of a bungalow, so that when the low-rise users of the building use hot water, the The hot water time is slow, which increases the waste of domestic water
