Embodiment 1

[0021] This embodiment provides a method for controlling the start-up of an air conditioner. figure 2 is the flowchart of the method, such as figure 2 As shown, the method includes:

[0022] Step 201: After the air conditioner satisfies the opening condition, monitor the rate of change of the environmental parameter;

[0023] Wherein, the environmental parameters involved in the present application may include ambient temperature, chilled water outlet temperature of the chiller, and ambient humidity.

[0024] Step 202: If the change rate of the environmental parameter is not less than the preset value, the control load device remains in the off state, and if the change rate of the environmental parameter is smaller than the preset value, the control load device remains in the open state.

[0025] Wherein, the load device involved in this application includes a fan, a water pump, and a solenoid valve in an air conditioner. It should be noted that the condition that the air...

Embodiment 2

[0037] This embodiment provides an air conditioner start-up control device, which is used to implement the above air conditioner start-up control method, Figure 4 is the block diagram of the device, as Figure 4 As shown, the device includes the following components:

[0038] The monitoring module 41 is used to monitor the rate of change of the environmental parameters after the air conditioner meets the opening conditions;

[0039] In this embodiment, the environmental parameters may include ambient temperature and ambient humidity.

[0040] The control module 42 is used to control the load device to remain closed if the rate of change of the environmental parameter monitored by the monitoring module 41 is not less than the preset value, and to keep the load device on if the rate of change of the environmental parameter is less than the preset value.

[0041] Optionally, the control module 42 may further include: a first control unit, which is used to control the load devi...

Abstract

The invention discloses an air conditioner power-on control method and device, so that at least the problem of frequent start-stop of a load device in the power-on process of an air conditioner in therelated technology is solved. The disclosed air conditioner power-on control method comprises the steps of monitoring the change rate of environmental parameters after the power-on conditions of theair conditioner are met; controlling the load device to be in the OFF state if the change rate of the environmental parameters is no less than a preset value; and controlling the load device to be inthe ON state if the change rate of the environmental parameters is less than the preset value. According to the air conditioner power-on control method disclosed by the invention, the problem of frequent start-stop of the load device under the influence of environmental factors is solved effectively, so that a compressor of the air conditioner is protected properly.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to an air conditioner start-up control method and device. Background technique [0002] figure 1 Shows the flow chart of starting the air conditioner, such as figure 1 As shown, when the conditions for turning on the air conditioner are met, the load devices such as the water pump, the fan, and the expansion valve are turned on, and the compressor is turned on after the turn-on time of these load devices reaches the compressor start-up delay time. However, before the turn-on time of these load devices reaches the compressor start-up delay time, due to large fluctuations in ambient temperature and other reasons, these load devices need to be turned off, which will cause the compressor unit to fail to start, but when the subsequent conditions are met, The load device will be turned on again, which will cause the load device to start and stop frequently, affecting th...
