Solar-assisted real-time regeneration system for anti-freezing solution of open heat-source tower

Abstract

The invention discloses a solar-assisted real-time regeneration system for an anti-freezing solution of an open heat-source tower. The system comprises an air inlet pipe I, a centrifugal fan, a solar air heat collector and an open heat-source tower heat pump system II. The air inlet manner is controlled, the anti-freezing solution in the open heat-source tower can be regenerated, and problems that the concentration of the anti-freezing solution gradually decreases and the freezing point rises during operation of a heat pump of the open heat-source tower are solved; real-time regeneration of the anti-freezing solution is realized, the heat pump is not required to be shut down, and the continuity of heat supply of the heat pump of the open heat-source tower in winter is kept. The solar air heat collector is added in the system, so that sensible heat exchange between air and the anti-freezing solution can be improved. An air type solution regeneration manner is adopted, the requirement of regeneration of the anti-freezing solution for high-grade energy sources is met, and complex equipment is avoided. The solar-assisted real-time regeneration system for the anti-freezing solution is integrated on the basis of the open heat-source tower, renewable energy sources are fully utilized, and large-scale application of solar and heat-source tower heat pump technologies is promoted.

technical field [0001] The invention relates to a solar energy-assisted heat source tower antifreeze instant regeneration system, specifically relates to heat source tower heat supply and antifreeze regeneration, and solar heat utilization technology. The practical problem of reducing the concentration has realized the instant regeneration of antifreeze, which has effectively promoted the application of heat pumps in open heat source towers. Background technique [0002] The heat source tower heat pump is a new type of heat pump device. It exchanges heat with the outdoor air through the heat source tower, absorbs the heat in the air, and converts the absorbed low-grade heat into high-grade heat in the form of a heat pump to achieve indoor heating and supply. Purpose of domestic hot water. Although the heat source of the heat source tower heat pump system also comes from the air, it is different from the way traditional air source heat pumps obtain energy from the air. In wi...

Problems solved by technology

However, it has the defects that part of the water vapor in the air is condensed into liquid water and enters the solution during operation, resulting in low antifreeze concentration and unstable freezing point. In addition, the solution concentration device in the actual project is equipped with a large configuration and high energy consumption. Limit the application of open heat source tower heat pump
