Embodiment Construction
[0030] In order to enable those skilled in the art to better understand the technical solution of the invention, the solution will be further described in detail below in conjunction with specific embodiments.
[0031] refer to figure 2 , the present invention provides a method for controlling air-conditioning and heating waterways, comprising the following steps:
[0032] First, obtain the engine cooling water temperature;
[0033] Then judge whether the engine cooling water temperature is lower than the set temperature threshold:
[0034] If the engine cooling water temperature is lower than the set temperature threshold, the first branch pipe circuit with the air conditioning heating core is opened, and the second branch pipe circuit without the air conditioning heating core is closed;
[0035] If the engine cooling water temperature is greater than or equal to the set temperature threshold, the working mode of the air conditioner needs to be detected. If the air conditi...

The invention relates to an engine cooling system technical field, and discloses an air-conditioning heating waterway control method; the method employs two waterways, and controls the waterways to open and close according to the engine cooling water temperature and an air-conditioning work mode, thus controlling the cooling water to pass a heating core of the air-conditioning or not, so the heating core of the air-conditioning under a refrigeration state cannot be overly heated by the cooling water, and thus affecting the refrigeration effect; the method also can prevent the heating core corrosion problem caused by long time no-flowing by of the cooling water. The invention also provides an air-conditioning heating waterway; a first branch pipe and a second branch pipe are connected in parallel between a first heating pipe connected with an engine water outlet and a second heating pipe connected with an engine water inlet; the air-conditioning heating waterway also comprises a pipe transition control unit controlling the first and second branch pipes to open and close; the heating core is arranged on the first branch pipe; the second branch pipe does not pass the heating core; the air-conditioning heating waterway has two waterways, so the work effect of the air-conditioning can be improved.
Description
technical field [0001] The invention relates to the technical field of engine cooling systems, in particular to an air-conditioning heating water circuit and a control method thereof. Background technique [0002] Existing engine cooling systems such as figure 1 As shown, it includes engine 1', radiator 2', thermostat 3' and water pump 4' on the circulation circuit, oil cooler 5' and EGR cooler 6' on the cooling circuit, and heating Heating core 7' on the circuit. On the heating circuit, the engine 1' is directly connected to the heating core 7' by pipelines, so the cooling water will circulate through the heating core 7' when the engine is running. In this way, even if the air conditioner is in the cooling mode, the heating core 7' will be heated by the cooling water, and the air conditioning components around the heating core 7' will also retain heat, which will reduce the cooling capacity of the air delivered by the blower and affect the air conditioner. Cooling effect...
