Abstract

The invention discloses a phase-change energy-storage bidirectional thermoregulation energy-saving ground heating component, which comprises a phase-change energy storage fitting and a hydraulic ground heating device or electric ground heating device, wherein the phase-change energy storage fitting is used with the hydraulic ground heating device or electric ground heating device. The phase-change energy storage fitting can be an energy storage tube or energy storage box containing phase change materials. In heat supply in winter, the phase-change energy storage fitting is high in energy storage capacity and capable of absorbing excessive heat in phase change, the thermal insulation effect is good, and temperature is automatically controlled; and in the process of heat dissipation, the temperature is maintained in a range comfortable for human bodies, repeated heating times of a heater and circulating times of hot water are reduced, and the problems that the common ground heating device is low in energy storage capacity, local temperature is over high and temperature fluctuation is high. In refrigeration in summer, the phase-change energy storage fitting absorbs a great deal of heat by phase change to lower the indoor temperature, and is also capable of absorbing and storing excessive cold of cold water pipes or a room and releasing the cold when the temperature rises.

Description

Technical field: [0001] The invention relates to the field of floor heating in HVAC engineering, and mainly relates to an energy-saving floor heating / cooling component that uses a phase-change energy storage material to perform bidirectional temperature adjustment for heating and cooling. Background technique: [0002] Floor heating is the abbreviation of ground radiation heating. Geothermal radiation heating is a heating method in which hot water or heating cables with a temperature not higher than 60°C are buried in the coil system under the geothermal floor to heat the entire ground, and radiate heat evenly to the room through the ground. The floor radiant heating system is currently the most comfortable, healthy and increasingly popular heating method in the world, with a service life of more than 50 years. You can choose to use the floor heating system in all areas of your home, and you can also choose to use it in some areas (such as bedrooms and halls). At present, t...
