Heating ventilation air conditioning facility capable of prolonging air outlet pipe opening structure

Abstract

The invention provides a heating ventilation air conditioning facility capable of prolonging an air outlet pipe opening structure, belongs to the technical field of heating ventilation air conditioning facilities. The invention aims to solve the problem that when dust and other sundries are cleaned on a filter screen at the bottom of an air outlet part in an existing heating ventilation air conditioning facility, a worker needs to manually complete cleaning through a climbing device, and then the convenience of cleaning the filter screen is reduced. The heating ventilation air conditioning facility comprises a top plate, a square pipe fitting is fixedly installed on the bottom end face of the top plate, a lower end connector of the square pipe fitting is connected with a retractable pipe fitting, a lower end connector of the retractable pipe fitting is connected with an air outlet piece, and a height adjusting mechanism is arranged between the exterior of the air outlet piece and the bottom end face of the top plate. By manually rotating an adjusting screw rod, the adjusting screw rod drives the air outlet piece to linearly move downwards under the action of threads in a threaded barrel, after the air outlet piece downwards moves to a proper height, the retractable pipe fitting is lengthened, and through the downwards-moved air outlet piece, the convenience of cleaning a filter screen at the bottom of the air outlet piece is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of heating, ventilating and air-conditioning facilities, and more specifically relates to a heating, ventilating and air-conditioning facility capable of extending the nozzle structure of the air outlet. Background technique [0002] HVAC is an air conditioner with heating, ventilation and air conditioning functions. Since the main functions of HVAC include: heating, ventilation and air conditioning, the comprehensive abbreviation of these three functions is HVAC. The HVAC system can control the temperature and humidity of the air and improve indoor comfort. It is an important part of medium and large industrial buildings or office buildings (such as skyscrapers). [0003] For example, application number: CN201810948323.1 The present invention discloses a HVAC pipeline connection device, including a first HVAC pipeline, a second HVAC pipeline, a pipeline connection device, an adjusting and fixing device, an...

Problems solved by technology

[0005] In order to solve the above technical problems, the present invention provides a HVAC facility that can extend the nozzle structure of the air outlet to solve the problem that the filter at the bottom of the air outlet in the existing HVAC facility is easily attached after a long period of use. There is a lot of dust and other sundries, and when cleaning these dust and other sundries, it needs to be manually completed through the climbing device, which greatly reduces the convenience of cleaning the filter at the bottom of the air outlet, and people are easy to fall from a high place when cleaning, thus The safety of cleaning the bottom filter of the air outlet is reduced, and when cleaning the bottom filter of the air outlet in existing HVAC facilities, dust and other sundries are easy to float up during the cleaning process, making it easy for cleaning personnel to Inhale these dust and other debris into the body, which will affect the health of the cleaning staff
