Description

Technical Field

[0001] The utility model relates to the technical field of air energy systems, in particular to an air energy buffer water tank that is free of cleaning and expansion. Background Art

[0002] At present, air energy systems are widely used in household heating and cooling. However, in the process of their design and installation, the structure of the air energy system is complex, and the installation space is limited. Especially when an expansion tank and filtration equipment need to be configured, more space is occupied, increasing the installation difficulty. Secondly, since the medium of the air energy system expands and contracts during temperature changes, it causes system pressure fluctuations and affects the stability of the system. In addition, impurities such as iron slag, molten plastic, and raw tape are generated during the operation of the system, and these impurities easily cause equipment blockage, increasing the maintenance cost and failure rate. Therefore, there is an urgent need for an air energy buffer water tank with the functions of being free of cleaning and expansion to simplify the system design, reduce the installation space and maintenance difficulty, and improve the stability and reliability of the system. Summary of the Invention

The circulation port of the buffer water tank includes a circulation inlet and a circulation outlet, and the stainless steel filter screen is installed at the circulation inlet and / or the circulation outlet.

[0009] Compared with the prior art, a semi-closed non-expansion tube is added to the upper exhaust port of the air energy buffer water tank. By using the non-expansion tube to lock a part of the gas in the cavity, the air energy buffer water tank has an expansion space, which can relieve the pressure fluctuation caused by the temperature change of the medium in the air energy system and ensure the stability of the air energy system. The non-expansion tube can automatically adjust the volume of the air energy buffer water tank when the temperature changes by locking part of the gas. The independent expansion tank in the air energy system is cancelled, saving the installation space of the system and improving the system utilization rate. A stainless steel filter screen is added to the circulation port of the air energy buffer water tank. The filter screen can be pulled out at any time for easy cleaning, reducing the installation of the Y-type filter in the air energy system, reducing the system maintenance workload and cost, and effectively protecting the air energy system.
