Abstract

The invention provides a test method for low-temperature start-up of an air-conditioning system. The air-conditioning unit is placed in a low-temperature environment to run statically. environment; the temperature of the low temperature environment is lower than the minimum operating temperature of the air conditioning unit. By placing the air-conditioning unit in a low-temperature environment lower than the minimum temperature of its work, because the temperature inside the air-conditioning unit has a greater temperature difference with the external environment, the migration speed of the refrigerant inside the air-conditioning unit is faster, and the refrigerant can be reached faster. Saturation temperature, and then move the air conditioner unit to the lowest temperature environment where it can work normally, so as to achieve low temperature cold start faster and improve work efficiency.

Description

technical field [0001] The invention relates to the technical field of air-conditioning testing, and more specifically, relates to a testing method for low-temperature start-up of an air-conditioning system. Background technique [0002] Air conditioners often encounter the situation of shutting down and standing still at night in winter during practical application. The air-conditioning unit starts after standing at low temperature for a certain period of time, and the unit has a short-term low-pressure phenomenon. Many air-conditioning units, especially commercial air-conditioning units, have low-voltage protection. When the unit’s low-voltage is too low, the unit will stop. Alarm, affecting customer use. [0003] In order to ensure the normal operation of the air-conditioning unit in a low-temperature environment, merchants need to conduct a low-temperature start-up test on the air-conditioning unit to test its normal start-up at low temperature. Usually, the air condit...
