Example Embodiment

[0012] Example 1: A certain brand of 3P cabinet, the evaporator is divided into 5 circuits, when the evaporator branch is not closed, the heating capacity is 7300W, and the system high pressure is 1.4Mpa during heating; when the bottom branch of the evaporator is closed, the heating capacity It is 7800W, and the system high pressure is 1.7Mpa during heating. The heating capacity is increased by 500W, nearly 7%.

Example Embodiment

[0013] Example 2: A certain brand of 2P is on-hook, the evaporator is divided into 4 circuits, when the branch circuit of the evaporator is not closed, the heating capacity is 4800W, and the high pressure of the system is 1.5Mpa during heating; when the branch circuit of the evaporator (the one with the smallest air volume) is closed , the heating capacity is 5200W, and the system high pressure is 1.8Mpa during heating. The heating capacity is increased by 400W, nearly 8.3%.

Abstract

The invention discloses a method for improving the heating ability of air conditioner, which is characterized in that the branch tubes of evaporator are mounted with valves; when refrigerating, the valves are open; when heating, the valves are closed partly. The invention can arrange evaporator inside volume-variable room, that closing some branches of evaporator when heating, to reduce the effective volume of evaporator to improve the high-pressure and improve the heating effect.
