In the multi-split air conditioner control, conditions such as the temperature of each indoor unit are different, so that the outdoor unit needs to know the state of each indoor unit, a number or an address needs to be set for each indoor unit, and the outdoor unit confirms which indoor unit operates or stops according to the number or the address so as to control the state of the indoor unit. For example, after the whole multi-split air conditioner control system is connected, the number or address of a plurality of connected indoor units can be set, specifically, the number or address can be set through dial switches connected to pins of a single chip microcomputer of a main control unit of the indoor units, the upper pin and the lower pin of the back face corresponding to each key in the dial switches are respectively dialed to one side of ON, the lower two pins are correspondingly connected, otherwise, the two pins are disconnected, and it is known through acquiring high and low levels ON the pins of the single chip microcomputer which bits in the dial switches are dialed or disconnected, for example, the indoor units are numbered, a first dial switch represents a ten digit, a second dial switch represents a single digit, the indoor units are numbered, of course, the coding rules can be set by themselves according to conditions, and no limitation is made here.
Hydraulic imbalance is divided into static imbalance and dynamic imbalance, wherein the static imbalance is caused by the fact that residual pressure heads exist in certain loops, namely when the resistance of certain loops is too small, the actual flow of the loops exceeds the designed flow, and because the total flow is constant, the other parts cannot reach the set flow, and uneven cooling and heating can occur; in a dynamic system, when the water amount of some loops changes, the pressure distribution of the system can be changed, so that other loops are interfered, and the principle that the other loops are not supposed to change to generate hydraulic balance, namely the principle of overcoming hydraulic imbalance is adopted, so that the purposes of saving energy and reducing consumption are achieved. In this embodiment, several indoor units are dragged by one outdoor unit, and when only one water module for floor heating is started, the hydraulic imbalance is caused by the small pressure in the water supply pipeline, so that the heating effect is poor. Therefore, in order to ensure the hydraulic balance of the floor heating system, the main control unit of the outdoor unit detects the number of closed electromagnetic valves, and when the number of closed electromagnetic valves is smaller than a preset number (for example, 50% of the total number of the electromagnetic valves), the outdoor unit sends a command to the floor heating main control unit to force the floor heating control unit to close the electromagnetic valves in the room without floor heating so as to ensure the water flow. The concrete implementation is as follows: the method comprises the steps that an address is set for an indoor unit in each room, the address of a floor heating water module and the address of a floor heating control unit in each room are the same as the addresses of the indoor units, the addresses of n rooms are sequentially set, when an outdoor unit main control unit detects that the number of currently closed electromagnetic valves is smaller than a preset number, the floor heating control unit is controlled to forcibly close M electromagnetic valves at each time according to address sequencing, the operation is circulated, the closing time of the M electromagnetic valves is not less than preset time (for example, 30 minutes), and M is larger than or equal to the preset number minus the number of the currently closed electromagnetic valves. At this time, the outdoor unit calculates the outlet water temperature of the water supply line according to the number of closed solenoid valves (including the number of solenoid valves closed by selecting the floor heating mode through the line controller and the number of solenoid valves forcibly closed) and the difference between T and Tset in each room.
For example, n =6, that is, the room 1 to the room 6, sets an address for the indoor unit of each of the rooms 1 to 6, and the floor heating water module and the floor heating control unit share the address, where the addresses of the rooms 1 to 6 may be from large to small or from small to large, which is not limited herein. An outdoor machine drags 6 indoor machines and floor heating water modules; if only the room 1 is opened with the floor heating water utilization module, 3 floor heating water utilization modules are not reached, the outdoor unit forcibly connects the electromagnetic valve in the room 2 and the electromagnetic valve in the room 3 through the floor heating control unit, the closing time of the electromagnetic valve in the room 2 and the closing time of the electromagnetic valve in the room 3 are kept to be more than or equal to 30 minutes, then the electromagnetic valve in the room 2 and the electromagnetic valve in the room 3 are forcibly closed, then the electromagnetic valve in the room 4 and the electromagnetic valve in the room 5 are forcibly connected for half an hour, then the electromagnetic valve in the room 6 and the electromagnetic valve in the room 2 are connected again, and therefore circulation is carried out, the total number of the connected electromagnetic valves is not less than 3, pressure in a water supply pipeline is guaranteed, meanwhile, heat in the room without the electromagnetic valve is.
As described above, the floor heating control unit is in communication with the outdoor unit and is used for monitoring data on a communication line from the line controller to the indoor unit, so that the floor heating control unit can be considered to be in communication with both the outdoor unit and the indoor unit, and both the line controller and the floor heating control unit are powered by the indoor unit. In another embodiment, when some users install the floor heating water module in some rooms (such as children's rooms) at the initial stage, but do not install the indoor unit, at this moment, the floor heating control unit cannot monitor data on a communication line from the wire controller to the indoor unit, therefore, a switch control circuit is added on the floor heating control unit, when the floor heating is needed, the switch control circuit outputs a first signal to the floor heating control unit, the floor heating control unit controls the electromagnetic valve to be closed after receiving the first signal, the floor heating is achieved, when the floor heating is not needed, the switch control circuit outputs a second signal to the floor heating control unit, and the floor heating control unit controls the electromagnetic valve to be opened after receiving the second signal. As shown IN fig. 5, the switch control circuit comprises a pull-up resistor R1, an emergency switch PSW1 and a pull-down resistor R2, one end of the emergency switch PSW1 is connected with the pull-up resistor R1, the other end is connected with the pull-down resistor R2, one input end IN of the floor heating control unit is connected between the other end of the emergency switch PSW1 and the pull-down resistor R1, wherein the pull-up resistor R1 is connected to a power supply signal VCC, when the emergency switch PSW1 is pressed, that is, the user wants to heat the floor, the pull-up resistor R1 pulls up the level at the point X1, so that the switch control circuit outputs a high level signal to the input terminal IN, the floor heating control unit communicates with the outdoor unit after receiving the high level signal, so that the outdoor unit is switched to or opens the water supply pipeline, the closing of the electromagnetic valve body is controlled according to the difference value between the set temperature Tset set by the floor heating control unit and the room temperature T, and the outdoor unit operates to heat according to the set temperature Tset; when the emergency switch PSW1 is lifted, namely, the user wants to stop floor heating, the pull-down resistor R2 pulls down the level at the X2 point to be the ground, the switch control circuit outputs a low level to the input end IN, and the floor heating control unit communicates with the outdoor unit after obtaining the low level, so that the outdoor unit is disconnected from a water supply pipeline, and the floor heating is stopped.
Because indoor set and drive-by-wire ware are not set up in the room, the floor heating control unit can' T monitor the settlement temperature Tset and the room temperature T that the drive-by-wire ware sent, and floor heating control unit is provided with settlement temperature Tset and temperature detection return circuit for detect room temperature T. If the outdoor unit and the indoor units need to communicate, the outdoor unit needs to know the address of each indoor unit, and under the condition that the indoor units are not arranged, the outdoor unit needs to know the address of the floor heating control unit, so that the outdoor unit can confirm which floor heating water module is running or stopped according to the address, and the control of the floor heating state is realized. After entire system connects, can number or address setting to a plurality of floor heating control units who connects, in this embodiment, floor heating control unit is provided with the address and sets for the return circuit, and this address sets for the return circuit and for example can use dial switch to connect on the pin of floor heating control unit's singlechip, just knows which position in the dial switch is dialled through the high-low level of gathering on the singlechip pin or has broken off, realizes the serial number or the address setting to floor heating control unit. In addition, the floor heating control unit provides an emergency switch for realizing floor heating control under the condition that no indoor unit exists, the possibility is provided for a user to select the indoor unit and the wire controller again, but when the indoor unit is installed, the number or the address of the indoor unit needs to be adjusted to be consistent with the current number or the address of the floor heating control unit, so that the communication between the indoor unit and the outdoor unit and the communication between the floor heating control unit and the outdoor unit are consistent. In addition, when the floor heating control unit, the indoor unit and the wire controller are all arranged, the room temperature T and the set temperature Tset in the wire controller are preferred, and the measured room temperature is inaccurate because the floor heating control unit is generally placed at a hidden position such as a kitchen and a floor heating pipeline joint.
According to the multi-split air-conditioning floor heating system and the control method, the floor heating control unit is used for monitoring a mode (an air-conditioning mode or a floor heating mode) sent to the indoor unit by the wire controller, when the floor heating mode is monitored, the floor heating control unit is communicated with the outdoor unit to enable the outdoor unit to open the water supply pipeline, meanwhile, the floor heating control unit controls the coil of the electromagnetic valve to be electrified, the valve body of the floor heating control unit is closed to enable the water supply pipeline to be communicated with the floor heating coil to achieve floor heating, when the air-conditioning mode is monitored, the floor heating control unit does not output signals to the control end of the electromagnetic valve, only timing communication with the outdoor unit is guaranteed, operation of the floor heating mode and the air-conditioning mode is achieved by the wire controller of the indoor unit.
