PATENT INTRODUCTION
专利介绍


Zhongsong Air Conditioning is deeply engaged in the research and development of refrigeration energy-saving technology, holding multiple industry original authorized patents, and building a complete technical barrier covering the four core tracks of installation, heat exchange, low-temperature heating, and new energy energy-saving. It has been awarded the title of National Science and Technology Enterprise Innovation Achievement.

The core flagship is the patented vacuum free installation, which innovates the refrigerant sealing pipeline structure. The factory uses micro positive pressure pre filled refrigerant with double-layer self sealing joints, completely eliminating the need for high-altitude vacuum pumping processes, avoiding installation leaks and efficiency degradation hazards. The relocation and reuse are stable and reliable, greatly reducing the probability of after-sales failures. Unique liquid cooling circulation heat exchange patent, which closed-loop cools the compressor with condensed water, solving the three major industry pain points of high temperature protection, operating noise, and outdoor dripping. Constant temperature heat dissipation improves the overall energy efficiency of the machine, and the operation is quiet, long-lasting, and durable.

Supporting * * Low temperature strong heat pump patent * *, expanding the applicable temperature range for heating and cooling, and providing fast and stable heating in extremely cold environments; There are also energy-saving invention patents such as solar AC/DC hybrid direct drive and refrigerant residual pressure recovery power generation, which achieve seamless switching between photovoltaics and mains power and significantly reduce electricity consumption. The entire series of patented technologies have been put into mass production, taking into account easy installation, comfortable use, and long-term power saving, driving technological upgrades in the air conditioning industry with independent core patents.

The first patent：No Extra Vacuum for Installation AC

Product feature: No need for additional vacuuming during air conditioning installation


[Installation side]
No need for a vacuum pump or on-site power connection for vacuuming. The only installation tool required is an Allen wrench. A single person can complete the standard hanging installation in 30 minutes, reducing labor time by over 50%;
To avoid after-sales failures caused by the master's laziness in not vacuumizing or not achieving the required standard during vacuumization, and to reduce installation disputes.
[Client]
The factory-assembled machine meets standard vacuum levels, with precise refrigerant ratio, ensuring both cooling and heating efficiency meet standards, and achieving long-term energy savings;
Prevent water vapor ice blockage in pipelines and corrosion of compressors, thereby extending the service life of the entire air conditioning system;
R32 and other refrigerant models eliminate the safety hazards associated with mixed gas installation.
[Channel Manufacturer Side]
Due to its convenient installation, it can significantly save installation costs, while also greatly reducing the need for repairs, returns, and exchanges caused by non-standard installation, thereby lowering the overall after-sales cost across the entire process. It is suitable for engineering centralized procurement and foreign trade bulk shipment scenarios.

Patent Liquid Cooling Air Conditioning

Zhongsong liquid cooled air conditioner



[Patented liquid cooling core technology]
Polymer liquid cooling closed-loop heat dissipation: The compressor is wrapped in a patented polymer cooling material, which combines with the condensed water from the unit to generate a semi-liquid cooling liquid. The operating temperature of the compressor remains constant within 100℃, effectively eliminating the common issues of high temperature overload and compressor thermal protection shutdown found in traditional air conditioners.
Closed-loop utilization of condensed water: All condensed water generated by the indoor unit is directed into the outdoor unit as a cooling medium, ensuring no water drips from the exterior of the entire system. This eliminates issues such as water seepage from external walls and water drips from the outdoor unit disturbing residents (closed-loop system where condensed water is self-produced and self-consumed).
The heat exchange efficiency of liquid cooling has been improved, with the heat exchange efficiency of evaporators and condensers increasing by about 10%, resulting in faster heat exchange between cold and hot fluids.
[Super energy-saving and power-saving]
Operating at low temperatures reduces power consumption for compressors, making the entire unit more energy-efficient compared to conventional air conditioners. Long-term use can significantly reduce electricity bills, and industrial and commercial models exhibit outstanding energy-saving advantages.
Secondary auxiliary heat dissipation of condensed water reduces the loss due to high-load operation of fans, ensuring more stable energy efficiency under all operating conditions.
[Silent shock absorption, comfortable experience]
The polymer liquid cooling material, with its damping and shock absorption effects, encapsulates the compressor to mitigate vibrations. Coupled with environmentally friendly soundproof cotton and shockproof foot pads, its operating noise is significantly lower than that of ordinary air conditioners.
The operating conditions of the unit are stable, with small fluctuations during startup and shutdown, ensuring low-noise operation around the clock in bedrooms, shops, and machine rooms.
