Title:
DIRECT WATER HEAT COLLECTIVE TYPE SOLAR HEAT UTILIZATION SYSTEM
Document Type and Number:
Japanese Patent JP2019095190
Kind Code:
A
Abstract:
To provide a solar heat utilization system capable of discharging freezing preventive water even if a certain level difference is present in heat collective pipes.SOLUTION: This invention relates to a direct water heat collective type solar heat utilization system having a device capable of discharging water in a solar energy collector and water in a solar energy collector pipe and preventing freezing of water. By providing an automatic discharging valve also opened when a loss of an electric power supply occurs and a device for forcedly sucking and draining by a blower residual water in the solar energy collector and the solar energy collector pipe that could not be fully removed through natural gravitational dropping after opening of the drain valve, it is possible to drain water without leaving any water. An air water separation tank is installed in front of the suction port of the blower in order to prevent the blower from being damaged upon suction of water into the blower.SELECTED DRAWING: Figure 6
