采用吸气管过热度调节的户式空气源采暖空调热水三用机

Household air source heating,air-conditioning & hot water packages regulated by the superheat degree of suction tube

简要介绍户式空气源采暖空调热水三用机的项目背景、技术原理、技术路线。针对三用机的特殊技术要求,首次提出吸气管过热度的定义以及采用电子膨胀阀PID调节吸气管过热度的新概念,利用该调节方法研制一台三用机,并按行业标准进行型式试验检测。测试结果表明,三用机达到国标的节能等级,并可高效制热、低温采暖,以及实现高效率的采暖、空调、热水、空调+热水等功能。

Briefly introduces the project background,technical principles and technical path of household air source heating,air conditioning hot water packages（HACW）,and puts forward for the first time the definition of the superheat degree of suction tube and the new concept of PID regulation of the superheat degree of suction tube with an electronic expansion valve aiming at special technical requirements of HACW.Researches and manufactures one HACW with this regulation method,and tests in line with industry standard of China.The test results show that the HACW is qualified in energy-saving grade as required in industry standards,and is capable of efficient heating,low-temperature heating,as well as efficient functions like heating,air conditioning,hot water and air conditioning hot water.
