Adjustable altitude enthalpy lab

The invention relates to an adjustable altitude enthalpy lab which comprises an enthalpy lab, an air drawing device, an air storage box body, a three-way control device and a pressure control system,wherein the air storage box body receives air exhausted from the air drawing device; an air inlet and an air outlet are formed in a wall of the enthalpy lab; the air drawing device is connected with the air outlet; and the three-way control device is arranged in the outlet position of the air storage box body. An air drawing mode is used for regulating the air mass relationship inside a lab, so that an enthalpy test lab can simulate different altitude change; the data testing is more accurate and convenient; the labor cost is reduced; in addition, the precision problem possibly caused by the test at different altitudes can be avoided; and for a user, the test cost is greatly reduced. 本发明涉及一种可调节海拔高度焓差实验室，包括焓差实验室、空气抽取装置、空气存储箱体、三通控制装置、压力控制系统，所述空气存储箱体接收空气抽取装置排出的空气；所述焓差实验室墙壁上设置有空气进口和空气出口，所述空气抽取装置与所述空气出口连接，所述空气存储箱体的出口处设
