Air source phase-change energy-storing floor air supply air-conditioning system and energy-storing and energy-releasing method thereof

Abstract

The invention discloses an air source phase-change energy-storing floor air supply air-conditioning system and an energy-storing and energy-releasing method thereof. The output end of an air source cold / hot water unit is connected with the input end of a water pump; the output end of the water pump is connected with the input end of an electric valve; the output end of the electric valve is connected with the cold / hot water input end of an air conditioner tank; the cold / hot water output end of the air conditioner tank is connected with the input end of the air source cold / hot water unit; the first air output end of the air conditioner tank is connected with the air input end of a room through a first pipeline; the air output end of the room is connected with the first air input end of the air conditioner tank through a second pipeline; and the second air input end of the air conditioner is communicated with the atmospheric air. Cold air with a low temperature at night in transition seasons can be stored through the energy-saving characteristic of a phase-change energy-storing material and can be released in the daytime by using the day-night temperature difference in the transition seasons, and the aim of saving energy is fulfilled. Energy can be stored at night and can be released in the daytime by using the peak-valley electrovalence difference in non-transition seasons, so that peak and valley loads are adjusted, and the running economy of equipment is improved.

Description

technical field [0001] The invention relates to an air source phase change energy storage floor air-supply air-conditioning system and an energy storage and release method thereof, belonging to the technical field of design and manufacture of refrigeration and air-conditioning systems. Background technique [0002] Intelligent buildings integrating modern office, communication, and automatic control have gradually emerged since the 1980s. The requirement that the interior must have a fresh, efficient, and comfortable environment has brought it a broad space for development and severe challenges. challenge. In recent years, the floor air-conditioning system has been favored for its flexible layout, strong adaptability, low energy consumption, and good air quality, which greatly adapts to the development needs of intelligent buildings. [0003] The floor air supply air conditioning system uses the space between the elevated floor and the floor as the air supply plenum, and th...
