A solar-assisted open heat source tower antifreeze instant regeneration system

Abstract

The invention discloses a solar-assisted open-type heat source tower antifreeze immediate regeneration system, which comprises an air inlet duct I, a centrifugal fan, a solar air heat collector and an open-type heat source tower heat pump system II. By controlling the air intake mode, the regeneration of antifreeze in the open heat source tower can be realized, which solves the problem that the concentration of antifreeze gradually decreases and the freezing point rises during the operation of the heat pump in the open heat source tower; the instant regeneration of antifreeze is realized without stopping the work of the heat pump , maintaining the continuity of heating in winter by the open heat source tower heat pump. Adding a solar air collector to the system is beneficial to improve the sensible heat exchange between the air and the antifreeze. The invention adopts an air-type solution regeneration method, which overcomes the demand for high-grade energy for antifreeze regeneration and avoids complicated equipment. On the basis of the open heat source tower, a solar-assisted antifreeze instant regeneration system is integrated to realize the full utilization of renewable energy and promote the large-scale application of solar energy and heat source tower heat pump technology.

Description

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
