Embodiment 1

[0032] refer to figure 1 As shown, the outdoor unit provided by the embodiment of the present invention also includes:

[0033] The first control unit 130 is used to control the solenoid valve to make the refrigerant flow through the first outdoor condenser 121 and the second outdoor condenser 122 to increase the heat exchange between the refrigerant and the outdoor air when the temperature of the indoor air needs to be lowered. The area increases the degree of heat exchange between the refrigerant and the outdoor air, reduces the temperature of the refrigerant when it flows out of the outdoor unit, and further reduces the effect and effect of the refrigerant on the indoor air in the indoor unit. Among them, the cooling The agent is used to regulate the temperature of the indoor air;

[0034] And / or when it is necessary to increase the temperature of the indoor air, the refrigerant flows through the first outdoor condenser 121 by controlling the solenoid valve to reduce the h...

Embodiment 2

[0054] The embodiment of the present invention provides a method for controlling the outdoor unit, which is used to control the outdoor unit 12 in Embodiment 1. Refer to Figure 6 shown, including:

[0055] S601. When the temperature of the indoor air needs to be lowered, the refrigerant flows through the first outdoor condenser and the second outdoor condenser by controlling the solenoid valve.

[0056] Step S601 increases the heat exchange area between the refrigerant and the outdoor air, improves the degree of heat exchange between the refrigerant and the outdoor air, reduces the temperature of the refrigerant when it flows out of the outdoor unit, and further reduces the flow rate of the refrigerant in the indoor unit. The action and effect of heating the indoor air, where the refrigerant is used to regulate the temperature of the indoor air;

[0057] S602. When it is necessary to increase the temperature of the indoor air, the refrigerant flows through the first outdoor ...

Embodiment 3

[0061] Embodiments of the present invention provide another outdoor unit control method, which is used to control the outdoor unit 12 in Embodiment 1. Refer to Figure 7 shown, including:

[0062] S701. When it is necessary to lower the temperature of the indoor air, close the first solenoid valve and open the second solenoid valve and the third solenoid valve, so that the refrigerant flows through the first outdoor condenser and the second outdoor condenser.

[0063] S702. Control the speed of the outdoor fan, and control the speed of the outdoor fan to increase when the temperature of the indoor air needs to be lowered.

[0064] S703. When it is necessary to increase the temperature of the indoor air, open the first electromagnetic valve and close the second electromagnetic valve and the third electromagnetic valve, so that the refrigerant flows through the first outdoor condenser.

[0065] S704. Control the rotation speed of the outdoor fan, and control the rotation speed ...

Abstract

The invention discloses an outdoor unit, an outdoor unit control method and an air conditioner system and relates to the field of air conditioners. The outdoor unit, the outdoor unit control method and the air conditioner system are used for solving the problem that the indoor air constant temperature effect achieved only by controlling the rotating speed of an outdoor draught fan is not ideal in the non-cooling and non-dehumidifying process. The outdoor unit comprises a first control unit which is used for making a refrigerant flow through a first outdoor condenser and a second outdoor condenser through a control electromagnetic valve when the indoor air temperature needs to be reduced, wherein the refrigerant is used for adjusting the indoor air temperature; and / or the control electromagnetic valve is used for making the refrigerant flow through the first outdoor condenser when the indoor air temperature needs to be increased. According to the embodiment, the outdoor unit, the outdoor control method and the air conditioner system are used for the non-cooling and non-dehumidifying condition of an air conditioner.

Description

technical field [0001] The invention relates to the field of air conditioning, in particular to an outdoor unit, a control method for the outdoor unit and an air conditioning system. Background technique [0002] When the air conditioner performs dehumidification, it mainly uses the principle of condensation of water vapor in the air to remove the water vapor in the air by cooling the air through the indoor heat exchanger. The side effect is to reduce the temperature of the air. In order to carry out dehumidification without cooling, the indoor heat exchanger is required to heat the air before or after cooling to compensate for the decrease in air temperature caused by the cooling process, so as to achieve a constant temperature of the indoor air. [0003] In the prior art, when performing dehumidification without cooling down, the heating effect of the indoor heat exchanger on the indoor air is controlled by controlling the speed of the outdoor fan, so as to compensate for ...
