Single well enclosed water exchangefresh air system with high efficiency

Abstract

The invention relates to a single well enclosed water exchange fresh air system with high efficiency which consists of a water-air mixing region, a water tank, a water medium circulating system, a sterilizing region, an air outlet-air return region, a water-air isolating plate, a felt filter screen and a control system; the water medium circulating system consists of a water return pipe, a water supply pipe, an underground well, a U-shaped pipe and a minitype heat exchanger; the water return pipe is connected with a drain valve of the water tank, the water supply pipe and a water inlet pipe are connected on a part located between a water inlet valve and the water return pipe, the water return pipe and the water supply pipe respectively extend to the underground well, and the U-shaped pipe is connected between the water return pipe and the water supply pipe; and the U-shaped pipe is immersed in the water body of the underground well, and the minitype heat exchanger is sleeved on the lower part of the pipe body of the U-shaped pipe. The single well enclosed water exchangefresh air system with the high efficiency can carry out heat exchange with a water medium in the U-shaped pipe continuously due to the fact that bottom water in the underground well can be kept at a constant temperature through geothermal energy, thereby realizing continuous supply of the water medium of constant-temperature and guaranteeing high heat exchange efficiency of the system.

Description

Technical field: [0001] The invention relates to an air exchange system, in particular to a groundwater well with a small volume, and a miniature heat exchanger is installed on a U-shaped pipe submerged in the water body of the groundwater well to improve the heat exchange between the water body in the groundwater well and the water medium in the system. The efficiency of the exchange keeps the water medium in the system at a constant temperature to ensure a high-efficiency single-well closed water exchange fresh air system with high heat exchange efficiency. Background technique: [0002] The existing air exchange system using water as a medium to exchange heat with air has a higher heat exchange efficiency than the original heat exchange between air. However, in actual use, after a period of heat exchange between water and air as a medium, the temperature of the water changes, and the heat exchange efficiency decreases accordingly, and its high heat exchange efficiency can...
