JPS597899B2 - Auxiliary heater energization control device for air conditioners - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides control that provides both comfort and power saving during sleep during heating operation of a cooling/heating air conditioner.

Conventionally, when sleep operation is input, the ON point and OFF' point of the temperature setting of the auxiliary heater remain as they are, as shown in Figure 1, or the auxiliary heater is forcibly activated in conjunction with the sleep operation input, as shown in Figure 2. There are two ways to turn it off.

However, with the control method shown in Figure 1, if the user has set the temperature high, the auxiliary heater will be energized more often than necessary, and by energizing the auxiliary heater, the energy efficiency of the air conditioner will be reduced. (E.E.R.: around 1 for the auxiliary heater and around 2 for the compressor), so the total energy efficiency decreased.

Further, according to the system shown in FIG. 2, when used in a cold region or when the user has set the temperature high, there is a possibility that the system may not be able to maintain the room temperature at the set value due to insufficient performance.

The present invention eliminates the above-mentioned conventional drawbacks.

As shown in FIG. 6, the present invention provides an auxiliary heater energization control device including a room temperature input means for detecting the room temperature, and a compressor thermodetermination means for determining the thermo-on and off points of the compressor based on the value of the room vortex. a sleep switch manual means for detecting the start of sleep operation; a memory means for determining the energization state of the auxiliary heater; a thermo-off determination means for determining whether to stop energizing the auxiliary heater based on the room information; a thermo-on determining means for determining energization based on a room temperature; and a disconnecting means for receiving a signal indicating the energization state of the auxiliary heater from the storage means and switching the room temperature signal from the room input means to the thermo-off determining means and the thermo-on determining means, respectively. , blocking means for receiving a sleeping operation start signal from the sleeping switch input means and blocking a room temperature signal flowing to the thermo-on determining means; and controlling whether the auxiliary heater and the compressor are turned on or off by the storing means and the compressor thermo determining means. It is composed of a driving means for driving an auxiliary heater and a compressor in response to a signal, and operates according to the flowchart shown in FIG.

An embodiment of the present invention will be described below with reference to FIGS. 3 to 5 of the accompanying drawings.

In Fig. 3, the auxiliary heater 6 is turned on just before starting sleep operation.
If so, it will continue to be turned on.

However, when the chamber width rises and reaches the OFF' point of the auxiliary heater 6, the auxiliary heater 6 turns OFF, and even if the chamber width decreases, the ON point disappears, so the auxiliary heater 6 never turns ON. (However, if you cancel sleep driving, it will return to the original mode.)

). In addition, in the figure, there is a Topa P channel oven drain type microcomputer, 2 is an operational amplifier, 3 is a relay coil that turns on and off the auxiliary heater 6k, 4 is a relay coil that turns on the compression block 7, 01"F', 3/, 4' are contacts of the relay coils 3 and 4, respectively, and 5 is a thermistor for room vortex detection.

A, B, and C are voltage waveforms shown in FIG. 5, respectively.

OUT, ~5 are the output terminals of the microcomputer 1, which generate scanning outputs OUT1~3rL, and
A stepwise waveform as shown in is synthesized, and this level is compared with the flatness-human strength level from the room vortex detection thermistor 5 by the operational amplifier 2, and the sequential output generation B is output by the microcomputer 1.
Enter the IN.

Then, the microcomputer 1 determines the current indoor sublevel based on the output timings of OUT1 to OUT3 and the timing of IN and manual pumping type B.

Here, the temperature scan level A is the temperature of the compressor 7 as shown in FIG.
OUT4, oUT4 and oUT4 are given meanings such as ON, OF"F, etc. depending on which point of level A is exceeded.
The output of the UT 5 is controlled, and the relays 3 and 4 are driven by the inverters 8 and 9.

With the above circuit operation, the control device of the present invention can be realized by preventing the ON point of the heater 6 from being read by the internal program of the microcomputer 1 shown in FIG. 7 when the sleeping power is IN2K.

According to the present invention, when the load is relatively large, the auxiliary heater is turned on at the start of sleep operation to quickly raise the room temperature to the set temperature, and as a result, when the room temperature reaches the set flatness,
In other words, if the capacity of the air conditioner exceeds the load, the auxiliary heater will not be turned on, and only the compressor will run in q-sequential operation, allowing for energy-efficient operation.On the other hand, if the load is relatively light, In a short period of time, only the compressor is in intermittent operation, resulting in an excellent effect of maintaining the chamber width at the set value while saving power.
