How to Improve the Performance of Automobile Air Conditioning and Heating

Abstract

The invention discloses a method for improving the heating performance of an automobile air conditioner. The air intake of the automobile air conditioner system has three states, which are respectively an internal circulation state, an external circulation state and an intermediate compensation state. The method mainly utilizes the intermediate compensation state to improve the heating performance ; The method includes the following steps: in response to the vehicle being powered on to the ON gear, judging whether the current temperature setting is a heating state; if it is a non-heating state, then judging whether the current mode of the HVAC air inlet is set to an external circulation state, if , then control the circulation damper to the external circulation state, if not, control the circulation damper to the internal circulation state; if it is in the heating state, then judge whether the current mode of the HVAC air inlet is set to the external circulation state, if not, control the circulation The damper is in the internal circulation state, if so, then judge whether the current gear of the blower is greater than the preset gear, if so, control the circulation damper to the intermediate compensation state, if not, then control the circulation damper to the outer circulation state. The invention can effectively improve the heating performance of the air conditioner.

Description

technical field [0001] The invention belongs to the field of automobile air conditioners, and in particular relates to a method for improving the heating performance of an automobile air conditioner. Background technique [0002] With the improvement of power technology, the engine is increasingly pursuing excellent power economy, which also brings some adverse effects. For example, after the engine efficiency is improved, the calorific value of the engine itself is further reduced, thereby reducing the engine water temperature, resulting in poor heating effects that rely on the engine water temperature. In most cold northern regions in winter, the heating demand for automotive air conditioners is strong, which cannot be met. User comfort needs. [0003] In order to improve the heating performance of the air conditioner, traditional cars often use auxiliary heating equipment to improve the heating effect, such as PTC heaters, fuel auxiliary heaters, etc. Although they can s...

For example, after the engine efficiency is improved, the calorific value of the engine itself is further reduced, thereby reducing the engine water temperature, resulting in poor heating effects that rely on the engine water temperature. In most cold northern regions in winter, the heating demand for automotive air conditioners is strong, which cannot be met. user comfort needs

[0003] In order to improve the heating performance of the air conditioner, traditional cars often use auxiliary heating equipment to improve the heating effect, such as PTC heaters, fuel auxiliary heaters, etc. Although they can significantly improve the heating effect, the price of the heater itself is basically more than 300 yuan. Moreover, the process of using the car will also generate additional energy consumption, which will greatly increase the cost of the user's car purchase and use.

If no auxiliary heating equipment is used, the traditional HVAC technology will use electronic water valves, increase the heat transfer capacity of the heater core and other means to improve the water temperature and heating effect of the heater core, but the development cycle and development cost are relatively long. high
