Water-ring phase-change energy-storage under-floor air distribution air-conditioning system and energy storage and energy release method thereof

Abstract

The invention discloses a water-ring phase-change energy-storage under-floor air distribution air-conditioning system and an energy storage and energy release 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 a first electric valve and the input end of a second electric valve respectively; the output end of the first electric valve is connected with the cold / hot water input end of an air handling unit; the cold / hot water output end of the air handling unit is connected with the input end of the air source cold / hot water unit; the output end of the second electric valve is connected with the input end of a phase-change energy-storage rectifying device; the output end of the phase-change energy-storage rectifying device is connected with the input end of the air source cold / hot water unit; the first air output end of the air handling unit 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 handling unit through a second pipeline; and the second air input end of the air handling unit is communicated with the atmosphere. By the system and the method, a cold / hot load during the day can be transferred to the night with low electricity price by utilizing the difference between peak electricity price and valley electricity price; the difference between a peak electric load and a valley electric load is relieved; and the economical efficiency of equipment operation is improved.

Description

technical field [0001] The invention relates to a water ring type phase change energy storage floor air-supply air-conditioning system and an energy storage and release method thereof, belonging to the technical field of refrigeration and air-conditioning system design and manufacture. Background technique [0002] Since the 1980s, intelligent buildings have gradually emerged. It integrates modern office, communication, and automatic control, and requires a fresh, efficient, and comfortable environment inside. Due to its flexible system layout, strong adaptability, low energy consumption, and good air quality, the floor air-conditioning system has attracted more and more attention. [0003] The floor air-supply air-conditioning system uses the space between the raised floor and the floor as the air-supply plenum, which sends the air into the room through pressure, and the ample space of the plenum can be used as a channel for cables and communication lines. The floor air-co...

AI Technical Summary

Problems solved by technology

These phase change energy storage methods cannot be organically combined with the existing air conditioning system, and a separate system needs to be set up, which has a complex structure, and the initial investment and operation and maintenance costs of the equipment are also relatively large.
