Abstract
The invention discloses an automatic temperature control and energy saving method for a 72 V electric automobile air conditioner heating system. An indoor temperature sensor is arranged in an air conditioner ventilation system. The method comprises the steps that (1) the air conditioner heating system is started; (2) a passenger sets the temperature through an air conditioner panel; (3) the percentage of relay unit time high frequency absorption time and unit time is controlled according to the temperature difference X of the temperature sensed by the indoor temperature sensor and the temperature set by the passenger. The automatic temperature control and energy saving method for the 72 V electric automobile air conditioner heating system adopts one relay, the absorption time in the unit time is controlled by the high frequency absorption and disconnection of the relay, all-time absorption shows PTC full power operation, and halftime absorption shows half power operation, so that the temperature in the automobile is automatically controlled, and the rapid heating time of the whole vehicle cannot be sacrificed by the technology.
Description
Technical field
The invention belongs to air conditioner energy saving field, specifically the temperature automatically controlled power-economizing method of a kind of 72V electric automobile air conditioner heating.
Background technology
72V electric automobile air conditioner heating major part adopts the mode of ptc heater heating, control mode has two kinds: 1. air-conditioner controller is divided into a gear or many grades by the opening and closing controlling one or more relay PTC, easy realization, but vehicle interior temperature fluctuation is large, and passenger comfort is poor; 2. air-conditioner controller is by the electrodeless control of metal-oxide-semiconductor, and actualizing technology difficulty is high.
Summary of the invention
In order to solve the above-mentioned technical problem existed in prior art, the invention provides the temperature automatically controlled power-economizing method of a kind of 72V electric automobile air conditioner heating, being provided with indoor temperature transmitter in air conditioner ventilating system, comprising the steps:
(1) air-conditioning heating system is opened;
(2) occupant is by air-conditioning panel set temperature;
(3) percentage of control relay unit interval high frequency adhesive duration and unit time is carried out according to the temperature of indoor temperature transmitter sensing and the temperature difference X of set temperature of occupant.
Further, described air-conditioning heating system adopts ptc heater heating.
Further, described ptc heater, main body adopts the PTC of parallel-connection structure and peripheral components combination to form by one or more pieces.
Further, if X > 10 DEG C, the percentage of relay unit interval high frequency adhesive duration and unit time is 100%.
Further, if 7 DEG C of < X≤10 DEG C, the percentage of relay unit interval high frequency adhesive duration and unit time is 90%.
Further, if 5 DEG C of < X≤7 DEG C, the percentage of relay unit interval high frequency adhesive duration and unit time is 80%.
Further, if 3 DEG C of < X≤5 DEG C, the percentage of relay unit interval high frequency adhesive duration and unit time is 70%.
Further, if 1 DEG C of < X≤3 DEG C, the percentage of relay unit interval high frequency adhesive duration and unit time is 60%.
Further, if 0 DEG C of < X≤1 DEG C, the percentage of relay unit interval high frequency adhesive duration and unit time be 60% ~ 0% with temperature difference X linearly.
Further, if X=0 DEG C, the percentage of relay unit interval high frequency adhesive duration and unit time is 0%.
The temperature automatically controlled power-economizing method of 72V electric automobile air conditioner heating of the present invention adopts a relay, by adhesive and the disconnection of this relay high frequency time, control the duration of adhesive in the unit interval, adhesive is always exactly PTC Operation at full power, it is about that half-power is run that adhesive duration accounts for half, thus automatically control vehicle interior temperature, what this technology can not sacrifice car load heats the time fast.
Accompanying drawing explanation
Fig. 1 is the temperature automatically controlled energy-conservation control circuit figure of 72V electric automobile air conditioner heating of the present invention;
Fig. 2 is the temperature automatically controlled Energy Saving Control flow chart of 72V electric automobile air conditioner heating.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As illustrated in fig. 1 and 2, the temperature automatically controlled power-economizing method of 72V electric automobile air conditioner heating of the present invention, adopt ptc heater, main body adopts the PTC (thermistor potsherd) of parallel-connection structure and peripheral components combination to form by one or more pieces, adopts blower fan to make the heater of air flowing heating.
First with the opening and closing of 1 solid-state relay control PTC.An indoor temperature transmitter is increased in air conditioner ventilating system.Occupant is by arranging the temperature on air-conditioning panel: if set temperature is higher than (winter can continue this phenomenon) during environment temperature always, and air-conditioner controller can control PTC adhesive, so just reaches the object automatically heated.Then the temperature difference of temperature arranged according to temperature and the occupant of indoor temperature transmitter sensing carrys out the percentage of control relay unit interval high frequency adhesive duration and unit time.
Here is a kind of vehicle, and relay, PTC high frequency attracting state control mode, be only limitted to reference:
This method controls simple; Components and parts are few; Precise control, can meet the requirements of temperature by the time of adhesive and the time of disconnection, be effective by the mode of infinite tendency; The vehicle interior temperature little comfort level that fluctuates is high, the temperature value gathered by indoor temperature transmitter, and this control method can directly level off to and infinite approach setting value.
