Abstract
(EN)
An air conditioning system. A first evaporator (401) and a second evaporator (402) are connected in parallel. A first electronic expansion valve (501) is serially connected to the first evaporator (401), and a second electronic expansion valve (505) is serially connected to the second evaporator (402), so that the opening degrees of the first electronic expansion valve (501) and the second electronic expansion valve (505) can be separately adjusted, the first electronic expansion valve (501) and the second electronic expansion valve (505) can perform position correction according to valve opening position information of the first electronic expansion valve (501) and the second electronic expansion valve (505) stored by the air conditioning system, and separately adjust target positions to calibrated target positions. The air conditioning system can reduce risks of out-of-synchronization of the electronic expansion valves and optimize performance of a control system. Also disclosed are a control system and a control method for the air conditioning system.

La présente invention concerne un système de climatisation. Un premier évaporateur (401) et un second évaporateur (402) sont reliés en parallèle. Un premier détendeur électronique (501) est relié en série au premier évaporateur (401), et un second détendeur électronique (505) est relié en série au second évaporateur (402), afin que les degrés d'ouverture du premier détendeur électronique (501) et du second détendeur électronique (505) puissent être réglés séparément, le premier détendeur électronique (501) et le second détendeur électronique (505) pouvant effectuer une correction de position en fonction des informations de position d'ouverture de valve du premier détendeur électronique (501) et du second détendeur électronique (505) stockées par le système de climatisation, et ajuster séparément les positions cibles à des positions cibles étalonnées. Le système de climatisation peut réduire les risques de désynchronisation des détendeurs électroniques et peut optimiser l'efficacité d'un système de commande. L'invention concerne également un système de commande et un procédé de commande pour le système de climatisation.
