A phase-change energy-saving anti-fog window and a window anti-fog control method

Abstract

The invention discloses a phase change type energy-saving antifogging window and a window antifogging regulating and controlling method. The phase change type energy-saving antifogging window comprises an inner-layer window body and an outer-layer window body which are mounted on a wall. The inner-layer window body and the outer-layer window body are arranged in a mutually spaced mode to form an air flow cavity. Air outlets and air inlets which face indoors or outdoors at the same time are formed in the upper portion and the lower portion of the air flow cavity correspondingly and all communicate with the air flow cavity. The phase change type energy-saving antifogging window further comprises a heat pump device. The heat pump device comprises a condenser, a compressor, an evaporator and a throttling valve. The condenser and the compressor are disposed below the air flow cavity, the evaporator is disposed outdoors, and the throttling valve is disposed between the condenser and the evaporator. The phase change type energy-saving antifogging window has the advantages that the antifogging effect is good; the heat bridge effect can be effectively relieved; the service life of a building is better prolonged; the energy consumption is low; and thermal comfort of indoor living is better improved. By means of the window antifogging regulating and controlling method, glass fogging can be effectively prevented, and the thermal comfort of indoor living is improved.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a phase-change energy-saving anti-fog window and a window anti-fog control method. Background technique [0002] With the improvement of people's living standards, people's requirements for the comfort of the living environment are getting higher and higher, especially some high-end villas are equipped with constant temperature and humidity systems to intelligently adjust the indoor temperature and humidity. In order to achieve the best effect of the constant temperature and humidity system, it is necessary to reduce the influence of the outdoor environment on the indoor temperature and humidity. However, in modern buildings, windows are the weak point of thermal insulation and energy saving, and they are also parts of high energy consumption in buildings. Statistics show that 40% of residential energy consumption in my country is caused by windows. [0003] The main functio...

Problems solved by technology

Because the insulation of windows is generally worse than that of walls, people sitting in front of the windows will obviously feel the cold and heat radiation from the surface of the window on their parts. feel uncomfortable

[0006] In order to solve the above problems, some anti-fog windows have been proposed. For example, the Chinese patent with the publication number CN202544700U uses the method of electrically heating the window glass for anti-fog. The simple electric heating method is very simple and convenient, and can also achieve the anti-fog effect. High energy consumption

The Chinese patent with the publication number CN203755965U uses a desiccant to remove moisture in the air to prevent window fogging. However, the desiccant is a consumable item. If it is not replaced after absorbing enough water, the moisture contained in it will evaporate into the air again. However, it will not only fail to achieve the desired defogging effect, but will aggravate the fogging phenomenon, so it is often necessary to replace it frequently, which is troublesome and will increase additional expenses.
