Description

Technical Field

[0001] The embodiments of the utility model belong to the technical field of condensate sampling devices, and more specifically, relate to a condensate sampling device suitable for use in a narrow space in a centralized air conditioner. Background Art

[0002] The "Sanitary Standards for Central Air Conditioning and Ventilation Systems in Public Places" stipulates the requirements for sanitary inspection of central air conditioners. The standard stipulates: "In each central air conditioning and ventilation system, cooling water, condensed water and water used in spray or cold water evaporation humidification should be inspected at no less than one location each". And the relevant standards stipulate that "the condensed water sampling point is set at the drain pipe or condensed water tray" and "each sampling point takes about 500ml of water sample according to aseptic operation". The condensed water of the central air conditioning and ventilation system in public places is mainly formed by the cooler coil during the heat exchange process. The formed cooling water is concentrated by the condensed water tray located directly below the cooler, and will eventually flow into the municipal pipe network drainage system from one port of the condensed water tray. During the on-site condensed water sampling work, due to the particularity of the position of the air conditioner fan coil and the slow process of condensed water formation, the sampling of condensed water for central air conditioning is extremely difficult. For this reason, it is particularly urgent to develop a sampling device suitable for condensed water from central air conditioner fan coils.

[0003] In order to solve the above technical problems, the on-site condensate water sampling method usually involves manually inserting cotton cloth into the outlet of the condensate water tray with the help of a rod. After a long period of waiting, the condensate water is gathered and accumulated to a certain amount. The condensate water in the condensate water tray is then manually drawn into the prepared water bottle with the help of a syringe several times until 500 ml is reached, completing a centralized air conditioning condensate collection.

[0004] Although the above method effectively realizes the centralized air conditioning condensate collection operation, the following technical problems or areas for improvement still exist: (1) The method used on site requires the completion of the outlet sealing, water storage waiting, and syringe water extraction processes one by one. The staff needs to stay for a long time to extract water at the sampling point, resulting in a large amount of invalid waiting time; therefore, with the help of automation technology, the process integration and automation operation can be completed, which can liberate the staff from ineffective labor to a certain extent; (2) Due to the small space of the condensate tray, the on-site tray sealing process is more difficult to operate, so a more novel water collection method should be adopted to omit the tedious process of tray sealing; (3) Regarding the improvement directions mentioned in (1) and (2), it should be considered to avoid the previous sampling from contaminating the sampling equipment when sampling at different sampling points, causing the subsequent sampling process to be affected. Therefore, disposable components can be set to solve this problem. Utility Model Content
