Process for removing water or steam for general family-type central air conditioning system pipeline and its control system

Abstract

This invention discloses a clean-up technique for pipes, water and gas of central air conditioning system of general household type and its control system which applies the method of line-up according to the length of pipes then to set nitrogen charging time, setting shortest pipe time such as five seconds as the primary standard to assign the time with refrigerant automatically according to the proportion of time / length to the branch pipes of each indoor machine to circulate in this way till finishing the charging. The invented automatic controly system is composed of several control circuit boards and a handheld controller, the control circuit boards include an interface, a central processor, a driving module and an electronic expansion valve and the handheld controller contains an interface, a central processor, a liquid crystal driving module and a liquid crystal display.

Description

technical field [0001] The invention relates to a process and an automatic control system for removing water and gas in pipelines of a general-purpose household central air-conditioning system. Background technique [0002] In the general-purpose household central air-conditioning installation specifications at home and abroad, it is required to vacuumize the fluorine circulation pipeline in the central air-conditioning system, and the longer the pipeline, the higher the vacuum required. The purpose is to remove the gas that has nothing to do with the refrigerant in the pipeline. (substance), especially water vapour. This process is complicated to operate, and the process is time-consuming, laborious, energy-consuming, and expensive. Especially, the actual conditions of the construction sites of each air conditioner and the length and thickness of the pipelines are different, so that the completion of this process depends on the technical level and responsibility of the spec...

Problems solved by technology

This process is complicated to operate, and the process is time-consuming, laborious, energy-consuming, and expensive. Especially, the actual conditions of the construction sites of each air conditioner and the length and thickness of the pipelines are different, so that the completion of this process depends on the technical level and responsibility of the specific operator. The heart has a direct correlation, and the quality of operation is easily affected by objective and human factors, which affects the installation quality of the general-purpose household central air-conditioning system, affects the construction quality of the general-purpose household central air-conditioning system, and makes the general-purpose household central air-conditioning system in The cooling (heat) capacity in actual operation does not meet the rated requirements
