Constant temperature and humidity device for passive house

Abstract

The invention discloses a constant temperature and humidity device for a passive house. A roof of the passive house is in an open type, and the house body of the passive house is of a double-layer structure. A plurality of rainwater collection holes are formed in the bottom surface of the roof, and two side surfaces of the roof are coated with solar cell panels in an attached mode; a water circulation pipeline is arranged in a hollow layer of the house body. The rainwater collection holes are connected to rainwater collection pipes, and the tail ends of the rainwater collection pipes separately communicate with the water circulation pipeline and are connected with spray nozzles. A hydrothermal circulation branch is arranged on one side of the water circulation pipeline, and the hydrothermal circulation branch is connected with an electric hot water tank. An electric control box is installed on the side wall in the house body, and the electric control box is provided with a controller and a battery module. According to the constant temperature and humidity device, renewable energy sources from solar energy and rainwater are adopted, rainwater is collected to circulate in a sandwichstructure inside the house body, and the constant temperature and humidity environment in the house body is controlled in combination with sensor detection.

Description

Technical field [0001] The invention relates to the field of construction technology, and specifically discloses a constant temperature and humidity device for a passive house. Background technique [0002] The concept of "passive house" building was established on the basis of low-energy buildings in Germany in the 1980s. Passive house is a master of various technical products. By making full use of renewable energy, the total amount of primary energy consumed is not Houses exceeding 120 kW·hour / (square meter·year). Such a low energy consumption standard is achieved through high heat insulation, sound insulation, strong airtight building exterior walls and renewable energy sources. "Passive house" is a new energy-saving building concept advocated abroad, and it is also an important opportunity and platform for my country to promote building energy-saving work. [0003] However, most of the exterior walls of existing passive houses have high thermal conductivity, poor thermal ins...
