Problems solved by technology

[0004] In order to solve the above problems, the present invention provides a buried pipe energy-saving ventilation system to solve the problem that the fresh air ventilator is directly connected to the outdoor fresh air, which is easily damaged in a cold environment. At the same time, it also solves the problem that the existing soil energy During the rainy season when the system exists, there are often problems with underground rainwater recharging and backflow into ventilation pipes

Embodiment

[0020] When the inventor carried out the installation experiment and application of the soil energy utilization system in Dalian area, he found that: due to the large temperature difference and high humidity in the buried ventilation pipe 20 in summer, condensation water is easy to form on the inner wall of the pipe. Therefore, the inventor aimed at the existing soil energy utilization system. The system adds drainage pipes and sumps 40 to discharge the frost and condensed water in the pipes; in the rainy season, in order to prevent the frequent rainwater during the summer rainy season, the water remaining in the surface layer will flow backwards, causing rainwater recharge To solve the problem in the underground ventilation pipe 20, the inventor set up an outdoor rainwater well 30 with a size of 1mx1mx2m on the ground surface, and discharged the rainwater accumulated in the outdoor rainwater well 30 to the sump 40 below the ground 3m with a water pump 31. Inside; the gravity d...

Abstract

A buried pipe type energy-saving ventilation system comprises a fresh air ventilator, a sump (40) used for storing accumulated water, and a buried ventilation duct (20) obliquely inserted into a soil layer, the sump (40) is communicated with an outdoor catch basin (30), outdoor fresh air is fed into one end of the buried ventilation duct (20), the other end of the buried ventilation duct (20) is communicated with an air duct (21), the portion, connected with the air duct (21), of the buried pipe ventilation duct (20) is located in the sump (40), and the air duct (21) is connected with an outdoor fresh air inlet (11) of the fresh air ventilator (10). According to the buried pipe type energy-saving ventilation system, buffer preheating or refrigeration is carried out on fresh air entering the fresh air ventilator through the buried ventilation duct, and damage to the fresh air ventilator caused by cold air due to direct contact is reduced.

Description

technical field [0001] The invention relates to a ventilation system, in particular to an underground pipe energy-saving ventilation system. Background technique [0002] In modern buildings and houses, it is common to use fresh air ventilators for ventilation and ventilation. However, in some cold areas in winter, there are frost problems when using fresh air ventilators for ventilation, especially when the outdoor temperature is lower than 0 Celsius, the heat exchange efficiency of the fresh air ventilator drops significantly, and even the heat exchange core body appears frost and cracks, which seriously affects the heat exchange effect, increases the indoor heating load, and shortens the use of the fresh air ventilator life. [0003] In response to the above problems, some solutions for soil energy utilization systems have emerged. However, these systems often have the problem of underground rainwater recharging and backflow into ventilation pipes during the rainy season...
