Solar integrated Rankine-Rankine system floor heating device

Abstract

The invention discloses and relates to a novel floor heating device. The device integrates a solar heat-collecting system and a Rankine-Rankine circulation system, utilizes a boiler to perform auxiliary heating and belongs to the fields of solar photothermal utilization, power circulation and heat ventilation and air-conditioning utilization. The device has the characteristics that hot water in a heat storage water tank is mainly provided by the solar heat-collecting system; when the temperature of the heat storage water tank is lower than a certain temperature, the boiler is started to perform auxiliary heating; the heat storage water tank is connected with an organic Rankine circulation system generator and a floor heating coiled pipe sequentially to realize gradient utilization of energy sources; an expansion machine and a compressor adopt a coaxial connection structure, so the link of converting mechanical energy into electric energy is reduced and the conversion efficiency of the mechanical energy is effectively improved; a condenser on the side of the expansion machine is connected with an evaporator on the side of the compressor, so the utilization efficiency of the energy sources is improved by utilizing regenerative cycle; and the condenser on the side of the compressor and the floor heating coiled pipe are connected to realize heating. The device has the advantages of simple structure, remarkable energy-saving effect, convenience for control and the like.

Description

technical field [0001] The invention belongs to the fields of solar light and heat utilization, power cycle and heating, ventilating and air conditioning utilization, and in particular relates to a solar energy integrated Rankine-Rankine system floor heating device. Background technique [0002] A number of statistics show that the energy consumption of buildings accounts for about 30% of the total energy consumption in the world today, which is a major form of energy consumption, and the energy consumption for HVAC accounts for about 85% of building energy consumption. With the intensification of the energy crisis and the increasingly prominent environmental problems, minimizing energy consumption, reducing the emission of harmful substances, and making full use of renewable energy for heating and cooling have become the basic trends in the development of modern building technology. With the continuous improvement of people's living standards, people have put forward better...
