Abstract
The intermittent wind blowing controlled temp. control method for central air-conditioning system includes a temperature-sensing step for sensing room temp., a temp.-fetching step for fetching room temp. set value, an operation step for operating above two-step temp. difference value, wind blowing control step for controlling wind and motor control step for controlling wind blowing motor operation. The wind blowing control step includes continuous and intermittent wind blowing sections, and when the temp. difference value between the actual room temp. and set value is greater than or equal to reference value, said wind blowing control step uses the continuous blowing section to drive motor to blow wind, and when said temp. difference value is less than reference value, it uses the intermittent wind section to drive motor to make discontinuous low-speed wind blowing to obtain the action of balancing and regulating room temp..
Description
The present invention relates to a kind of central air conditioner system temperature control method, particularly relate to a kind of can regulate automatically and and then the balance cylinder in the central air conditioner system temperature control method controlled of the batch (-type) air-supply of temperature.
The aircondition of central air conditioner system can be divided into air-supply output and two kinds of kenels of cold air output basically in the past, that wherein general cold air output is is strong, in, weak syllogic adjusts wind speed, in order to reduce indoor temperature.Yet because that indoor cold air can flow out via slits such as crack between a door and its frames is indoor, and that outdoor hot-air also can be gone into from this slit flow is indoor, so, causes the loss of cold air easily.Because the design of aircondition in the past is to adopt the output of syllogic cold air, therefore the cold air output quantity of this syllogic, makes that air supply motor and the frozen water valve in the aircondition ceaselessly turns round all greater than the cold airflow vector, to reach the effect that reduces room temperature.When room temperature is reduced to the temperature value that aircondition sets, close the frozen water valve this moment, make frozen water no longer circulate in the frozen water pipeline, and air supply motor still keeps ventilation state, through a period of time Hou, when room temperature raise and surpass the temperature value that aircondition sets, the frozen water valve just began to start running again, cooperate the air-supply action of air supply motor, make aircondition be the cold air output state.Yet when the frozen water valve cuts out a period of time Hou, room temperature raises and surpasses set temperature value, and this moment is indoor will sultry gradually, and therefore, the frozen water valve restarts by the time, the Hou of still need waiting for a period of time, and indoor temperature just can have nice and coolly to be experienced.In addition, the temperature control method of aircondition was to reach the temperature control effect with the wind speed change that opens and closes the cooperation air supply motor of frozen water valve in the past, but because the present general Cui not of the water quality in the environment, after causing use a period of time, the frozen water valve produces corrosion or phenomenon of the failure such as stuck because of the impurity in the water easily, so not only lose the temperature control effect, more increase the puzzlement of maintenance.
Aforementioned when utilizing the frozen water valve to cooperate air supply motor to carry out temperature control for exempting, the frozen water valve is easy to generate erosion or phenomenon of the failure such as stuck, therefore another kind of aircondition does not promptly use the frozen water valve, make when room temperature reaches setting value, if air supply motor still continues air-supply, then because the frozen water frozen water pipeline that still continued to flow, cause room temperature still can continue to descend, if and air supply motor is out-of-blast when room temperature arrives setting value, then can not make indoor quick rise because of air does not flow again, and then produce sultryly, therefore need just can feel nice and cool, so this aircondition of frozen water valve that do not use can not effectively reach the temperature control effect through a period of time Hou.
Because aircondition all was only to have the effect that reduces room temperature in the past, shortcoming that but can't the balance indoor temperature, so, there is the dealer to grind and sets out-inverter motor, and this inverter motor is installed in the aircondition of central air conditioner system, make aircondition have high wind with the frequency conversion rotating speed that utilizes inverter motor, middle high wind, weak wind, four-part form wind speed such as gentle breeze, that is input voltage is given the step-down of different amplitudes by inverter motor, cause inverter motor can therefore produce the four-part form rotating speed, and when the rotating speed of inverter motor is tending towards the most weak, then aircondition can maintain the gentle breeze state, so, make indoor temperature reach poised state, still, inverter motor is used in the central air conditioner system, still has some shortcomings in practicality:
1. raising fringe cost:
Because the inverter motor structure is very complicated, its manufacturing cost is very high, quite wastes time and energy in making to produce, and makes the fringe cost of central air conditioner system improve.
2. fault rate height:
Because of inverter motor be input voltage is given different amplitudes step-down to cause four-part form wind speed such as high wind, middle high wind, weak wind, gentle breeze, change and the inverter motor repetitiousness is carried out step-down, so, cause the fault rate of inverter motor to improve.
Main purpose of the present invention be to provide a kind of can regulate automatically and and then the balance cylinder in the central air conditioner system temperature control method controlled of the batch (-type) air-supply of temperature.
The present invention is characterized in: this temperature control method comprises the temperature-sensitive step of a sensing room temperature in regular turn, one reads the temperature read step of setting value at room temperature, the calculation step of the temperature approach of one computing and the rapid gained of comparison first two steps, one controls the air-supply of blowing according to the operation result of previous step controls step, and one be connected with air supply motor control step with control air supply motor running with previous step, when the temperature approach between calculation step gained actual room temperature value and setting value at room temperature during more than or equal to a reference value, air-supply control step will be controlled air supply motor and continue air-supply, and when the temperature approach between calculation step gained actual room temperature value and setting value at room temperature during less than a reference value, air-supply control step is then controlled intermittently low speed air-supply of air supply motor, use balance and regulate the room temperature, make indoor temperature can reach the purpose of intending balance.
The central air conditioner system temperature control method of batch (-type) air-supply control of the present invention, the main temperature-sensitive step that comprises a sensing room temperature in regular turn, one reads the temperature read step of setting value at room temperature, the calculation step of the temperature approach of one computing and the rapid gained of comparison first two steps, one controls the air-supply of blowing according to the operation result of previous step controls step, and one be connected with air supply motor control step with control air supply motor running with previous step, wherein, air-supply control step includes and continues air supply section and air supply section intermittently, when the temperature approach between calculation step gained actual room temperature value and setting value at room temperature during more than or equal to a reference value, air-supply control step drives the air supply motor air-supply to continue air supply section, and when the temperature approach between calculation step gained actual room temperature value and setting value at room temperature during less than a reference value, air-supply control step is then with the intermittently low speed air-supply of air supply section drive at intermittence air supply motor, low speed air-supply at intermittence with the mat air supply motor, come balance and regulate the room temperature, make indoor temperature can reach the purpose of intending balance.
