Embodiment Construction

[0015] The content of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0016] As shown in Figure 2, the jitter-free room temperature control device includes a single-chip microcomputer PCB, a flow detection device TS, a temperature sensor RT, a multi-block switch KN, a four-way valve relay TF, a power supply, a capacitor C1, and resistors R1 and R2; After the sensor RT is connected in parallel with the capacitor C1, one end is grounded, the other end is respectively connected to the power supply through the resistor R1, connected to the AIN0 end of the single-chip PCB through the resistor R2, and the multi-speed switch KN is connected to the AIN2 end of the single-chip PCB. The multi-speed switch KN selects a precision 16-speed switch, which is used as a cooling capacity selection switch. The position of the cooling capacity selection switch is determined by the installation conditions of the air co...

Abstract

The present invention provides a shake-proof room temperature control device and control method thereof, a temperature sensor is in parallel connection with a capacitance, and an end connects to grounding, an end connects to power by resistance R1, to AIN0 terminal of singlechip by resistance R2 separately, multi-gear switch connects to AIN2 terminal of singlechip, the four-way valve relay connects to P0.1 terminal of singlechip, the P1.1 terminal of singlechip is set to be temperature signal terminal, the T0 terminal of singlechip connects to flux detection device and power, the PWM terminal of singlechip is output terminal of rotation speed control signal of the compressor of the air conditioner. The method comprising steps of adjusting the flux of the cool medium by sensing the slope of temperature variation curve indoors, controlling the refrigeration / heat of the air conditioner, the compressor stopping when set temperature is achieved. The invention automatically controls refrigeration / heat of the air conditioner to balance the heat exchange between indoors and outdoors according to temperature difference state and ventilation state of periphery circumstance.

Description

technical field [0001] The invention relates to a room temperature control method during cooling / heating of an air conditioner, in particular to a vibration-free room temperature control device and control method during cooling / heating of an air conditioner. Background technique [0002] Due to the diversity of the natural environment and people's living environment, in different environments, even if the temperature difference between the room and the outside is equal, the speed of the heat exchange is also different. Therefore, for different heat exchange environments, the expected cooling capacity for each temperature difference value is different, otherwise, under the condition of non-stop operation of the compressor, it will cause insufficient cooling or excessive cooling. As a result, the temperature in the room is lower or higher than the set temperature. Because the traditional air conditioner does not have a throttle valve device, the cooling capacity of the tradit...
