Description

Technical Field

[0001] The utility model relates to the technical field of air-conditioning boxes, and in particular to an air-conditioning box with built-in valves and filters. Background Art

[0002] The air-conditioning boxes of the existing central air-conditioning systems that use fan disks for cooling or heating do not include two valves for the pipelines entering and exiting the air-conditioning boxes, filters, flushing bypass pipes and bypass valves, electric regulating valves or electric two-way valves, pressure gauges, thermometers and corresponding connecting pipes, etc. Under normal circumstances, the two valves for the pipelines entering and exiting the air-conditioning boxes, filters, flushing bypass pipes and bypass valves, electric regulating valves or electric two-way valves, pressure gauges, thermometers, etc. are all designed by the design institute and then installed on-site by the installers. The workload of the assembly, production and installation of these various types of valves, filters, various components and pipes often occupies a large part of the entire air-conditioning water system pipeline network, and even if these pipes and pipe components are prefabricated in the factory and installed on-site, it is difficult to achieve accurate dimensions to meet the on-site installation. Due to the poor on-site installation conditions, more labor is often consumed and the cost is high. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide an air conditioning box with built-in valves and filters, which has a simple structure and integrates some valves, filters, various components and pipelines into the air conditioning box without increasing the size of the original air conditioning box, thereby improving product quality and reducing costs. After the two valves, filters, flushing bypass pipelines and bypass valves, electric regulating valves or electric two-way valves, pressure gauges, thermometers and corresponding connecting pipelines of the pipelines entering and exiting the air conditioning box are built-in, these must be placed outside the air conditioning box. The insulation layer and the protective layer outside the insulation must be constructed, and these placed inside the air conditioning box do not need to be insulated or the protective layer outside the insulation, which not only reduces the cost, but also does not require the insulation to be disassembled for maintenance, and the insulation layer and the protective layer outside the insulation must be restored after maintenance.

[0004] In order to solve the above technical problems, the utility model provides an air-conditioning box with built-in valves and filters, comprising an outer shell, in which an inlet pipeline assembly and an outlet pipeline assembly are arranged, the inlet pipeline assembly comprises an inlet pipeline control valve, a pressure gauge after the filter, an inlet pipeline filter, a pressure gauge before the filter and an inlet pipeline thermometer arranged in sequence; the outlet pipeline assembly comprises an outlet pipeline control valve, an outlet pipeline electric valve, an outlet pipeline pressure gauge and an outlet pipeline thermometer arranged in sequence; the bottoms of the inlet pipeline assembly and the outlet pipeline assembly are both connected to a cooling or heating coil, and a water pipe venting control valve is arranged between the outlet pipeline assembly and the cooling or heating coil.

[0005] Furthermore, a negative pressure sealed door for valve control is provided on the shell at positions corresponding to the outlet pipeline assembly and the inlet pipeline assembly, and a double-layer vacuum glass observation window is provided on the negative pressure sealed door for valve control.

[0006] Furthermore, it comprises a fan, a motor is arranged on one side of the fan, an air outlet is arranged on the top of the fan, and a negative pressure sealing door for maintenance is arranged on the casing at a position corresponding to the fan.

[0007] Furthermore, a bypass flushing control valve is provided between the inlet pipeline assembly and the outlet pipeline assembly.

[0008] Furthermore, a condensate discharge pipe and an air return port are provided at the bottom of the shell.

[0009] Furthermore, an external inlet pipeline and a flexible joint are arranged on the top of the inlet pipeline assembly.

[0010] Furthermore, an external outlet pipe and a flexible joint are arranged on the top of the outlet pipe assembly.

[0011] Beneficial effects of the utility model: the device integrates some valves, filters, various components and pipes into the air conditioning box without increasing the size of the original air conditioning box, and the air conditioning box manufacturing factory processes and manufactures them in place in the factory, which not only improves the product quality, but also reduces the cost of material cost and labor cost, because the mechanization and automation degree of the factory will be much higher. The utility model patent will build two valves, filters, flushing bypass pipes and bypass valves, electric regulating valves or electric two-way valves, pressure gauges, thermometers and corresponding connecting pipes into the pipeline in and out of the air conditioning box. These must be placed outside the air conditioning box. The insulation layer and the protective layer outside the insulation must be constructed. These do not need to be placed inside the air conditioning box. This reduces the cost, and the maintenance does not need to disassemble the insulation, and the insulation layer and the protective layer outside the insulation need to be restored after the maintenance. Especially for some engineering projects exported to foreign countries, the production cost of domestic factories in batches is more than half lower than the single cost of foreign sites.
