Description

Technical Field

[0001] The invention belongs to the technical field of HVAC equipment, and in particular relates to a building HVAC device utilizing solar energy. Background Art

[0002] A building HVAC device using solar energy refers to a system device that uses solar energy as an energy source for heating, ventilation and air conditioning inside a building. This device integrates key components such as solar collectors, heat storage devices, heat exchangers, and control systems to achieve effective collection, conversion and utilization of solar energy, thereby providing the required cold and heat sources and air conditioning functions for the building. The installation method of the existing HVAC outdoor unit usually relies on mounting frames, which are fixed on the outdoor wall to support and place the air conditioning outdoor unit. However, the current installation method mostly uses a bolt and nut combination method, and multiple sets of bolts need to be screwed into the nuts one by one to complete the fixation. This installation method is not only poor in stability, but also easy to shake during the installation process, affecting the installation accuracy, and the operation is cumbersome, increasing the workload of the installation workers and the outdoor operation time. Especially when working at high altitudes, long-term outdoor operation not only increases the physical exertion of the workers, but also brings greater safety hazards. Therefore, the existing HVAC outdoor unit installation method has obvious deficiencies in stability and convenience, and cannot meet the high requirements of modern buildings for installation efficiency and safety.
