Problems solved by technology

[0004] The purpose of the present invention is to provide an air-conditioning and heating method and device for a phase-change energy-storage ceiling, which can make the combination of phase-change materials and heat pumps more energy-saving and play the role of peak elimination and valley filling, so as to solve the problems caused by the use of heat pumps or refrigerators. The peak load of the power grid is too large. In areas where the peak and valley electricity prices are divided, the electricity bill can be greatly reduced, making heating in winter and cooling in summer more economical.

Embodiment Construction

[0018] The specific implementation of the present invention will be further described below in conjunction with accompanying drawing:

[0019] Such as figure 1 and figure 2 As shown, the air conditioner includes a heat pump 5 , a suspended ceiling 1 , a water pipe 3 connected to the heat pump and arranged between the suspended ceiling and the top floor of the room, a fixed phase change material 2 , an insulating material 4 and a regulating valve 6 . The insulation layer 4 is located under the top floor of the room; the shape-setting phase-change material 2 is under the insulation layer 4; the water pipes 3 are evenly distributed in the shape-setting phase-change material 2; 5 connection, the regulating valve 6 is installed on the water pipe 3. The heat pump can be an air source heat pump or a water source heat pump; the shape-setting phase change material is a shape-setting phase change material with a phase change temperature between 15°C and 35°C, for example, paraffin-po...

Abstract

The invention relates to a phase change energy storage floor air conditioner heating method and its device. It belongs to heating air condition technology field. In the invention, phase change material is adopted as energy storage medium to conduct suspended ceiling air condition and heating. Put phase change material between top floor slab and suspended ceiling. Hot water or cold water pipes connecting with heat pump or cold machine are set among phase change materials. When electric network is in its low valley, hot water or cold water generated by heat pump or cold machine makes phase change material store energy; when electric network is in its pinnacle, heat pump or cold machine stop working and use the storage energy to supply heat or cold for rooms.

Description

technical field [0001] The invention belongs to the technical field of heating and air conditioning, and in particular relates to a phase change energy storage ceiling air conditioning heating method and device. Background technique [0002] Ceiling heating and cooling have a large radiant area without shading, high energy utilization efficiency, and can save indoor space. It is suitable for residential and office buildings with low floor heights. Compared with full-air air conditioning systems, it reduces the need for air ducts. space, so that the building space can be used more effectively. Existing ceiling heating and cooling adopt the form of direct use of hot water or cold water pipes, without heat storage function. Because the system does not have heat storage, it cannot use the cheap electricity during the low power grid period. [0003] In recent years, heat pump technology has developed rapidly, and it is used more and more in heating and air-conditioning systems....
