Method and system for controlling residence primary air system

Abstract

The invention discloses a method and system for controlling a residence primary air system, and relates to the technical field of building energy saving. According to the method for controlling the residence primary air system, air in an exhaust pipeline communicating with an air conditioner room is heated through a solar PV / T heat collecting ring way, and cold air in a basement enters the room. The residence primary air system comprises the solar PV / T heat collecting ring way, the basement, the air conditioner room communicating with the basement and the exhaust pipeline communicating with the air conditioner room. The solar PV / T heat collecting ring way comprises an exhaust port coil pipe for heating the exhaust pipeline, and the air conditioner room communicates with the basement through an air inflow pipeline. The indoor primary air circulation capacity is improved, the equipment utilization rate is increased, the energy consumption of an air conditioner is reduced, and traditionalenergy is saved; and the utilization rate of a solar PV / T heat collector in non-heating seasons is increased, the solar photovoltaic photothermal conversion efficiency of the solar PV / T heat collector is guaranteed, and the service life of the solar PV / T heat collector is prolonged.

Description

technical field [0001] The invention relates to the technical field of building energy conservation, in particular to a method and system for controlling a residential fresh air system. Background technique [0002] Solar photovoltaic / thermal (PV / T) heating systems can give full play to the advantages of clean energy and reduce the fossil energy consumption of traditional heating systems. However, in summer and transitional seasons, the heat collected by the system cannot be effectively recycled, and the water temperature in the heat storage tank continues to rise, which reduces the cooling capacity of the photovoltaic panels of the flowing working fluid in the PV / T heat collector, resulting in photovoltaic The unfavorable working conditions of excessively high temperature of the panels and heat-absorbing panels will directly lead to a decrease in the photoelectric and photothermal conversion efficiency of the PV / T collector or even damage the panels, seriously affecting the...

Problems solved by technology

However, in summer and transitional seasons, the heat collected by the system cannot be effectively recycled, and the water temperature in the heat storage tank continues to rise, which reduces the cooling capacity of the photovoltaic panels of the flowing working fluid in the PV / T heat collector, resulting in photovoltaic The unfavorable working conditions of excessively high temperature of the panels and heat-absorbing panels will directly lead to a decrease in the photoelectric and photothermal conversion efficiency of the PV / T collector or even damage the panels, seriously affecting the service life of photovoltaic modules and PV / T collectors

In addition, in order to meet the demand for fresh air in traditional air-conditioned rooms, opening windows for ventilation or using ventilation equipment such as exhaust fans will cause a large loss of indoor cold air. consumption

At the same time, the air-conditioning in the basement of residential buildings has not been rationally utilized as a natural cooling source

The above-mentioned problems, on the one hand, seriously affect the comprehensive solar energy utilization efficiency of the solar PV / T heating system and the service life of the equipment, on the other hand, consume more traditional energy to meet the load demand of fresh air and air conditioning, while ignoring the natural cold source in the basement Reasonable use
