specific Embodiment 1

[0022] see figure 1 As shown, this embodiment proposes a constant temperature and humidity air conditioner. The air conditioner includes a main control module, an electric heating device connected to the main control module, a temperature sensor and a humidity sensor. The temperature sensor detects the indoor ambient temperature, the humidity sensor detects the indoor ambient humidity, and transmits the detection signal to the main control module. The state of the solenoid valve on the refrigeration pipeline controls the flow and direction of the refrigerant, controls the speed of the fan, etc., to control the intensity of cooling, heating, and dehumidification of the air conditioner. When the external ambient temperature is relatively bad and the heating capacity of the air conditioner itself is not enough to meet the requirements, the main control module can control the opening of the electric heating device to meet the heating demand. In this embodiment, a water tank is pr...

specific Embodiment 2

[0029] Such as figure 2 As shown, this embodiment proposes a constant temperature and humidity air conditioner, including a main control module, an electric heating device connected to the main control module, a temperature sensor, a humidity sensor and an alarm module. The temperature sensor detects the indoor ambient temperature, the humidity sensor detects the indoor ambient humidity, and transmits the detection signal to the main control module, and the main control module controls the operating status of the air conditioner, electric heating The start and stop of the device and the water pump, and control the alarm state of the alarm module.

[0030] Air conditioner refrigeration circuit. In the refrigeration circuit, there are compressors, four-way valves, indoor heat exchangers, outdoor heat exchangers and electronic expansion valves connected in sequence. Among them, the indoor heat exchanger and the outdoor heat exchanger correspond to the indoor fan and the outdoor...

Abstract

The invention relates to a constant-temperature and constant-humidity air conditioner and a control method of the constant-temperature and constant-humidity air conditioner. The constant-temperature and constant-humidity air conditioner comprises a main control module, an electric heating device, a temperature sensor and a humidity sensor, wherein the electric heating device, the temperature sensor and the humidity sensor are connected with the main control module. A water groove is formed in the electric heating device and communicated with a water tank through a water pump. The temperature sensor and the humidity sensor detect the environment temperature and the environment humidity respectively, generate detection signals and send the detection signals to the main control module, and the main control module controls the running state of the air conditioner, the working state of the electric heating device and the working state of the water pump. A humidifying device is integrated on the electric heating device. When humidification needs to be conducted, water is added into the water groove, the electric heating device is started, and water vapor is generated so that the humidification can be conducted. When humidification does not need to be conducted, no water is added into the water groove, and the temperature can be adjusted with the help of the electric heating device. Accordingly, the control module controls the working state of the electric heating device and the working state of the water pump according to the indoor temperature detected by the temperature sensor and the indoor humidity detected by the humidity sensor so that the indoor constant temperature and the indoor constant humidity can be achieved.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to an air conditioner capable of realizing constant temperature and humidity and a control method for the air conditioner. Background technique [0002] Existing air conditioners generally have a dehumidification function on the basis of temperature regulation, so as to achieve the effect of regulating indoor temperature and humidity. The air conditioner has a dehumidification effect in cooling or dehumidification mode, and the flow direction of the refrigerant in the refrigeration pipeline is the same in the dehumidification operation mode and cooling operation mode of the air conditioner. Therefore, the existing air conditioner has no dehumidification and cooling operation mode The essential difference is that the fan in the control room operates at a slightly lower wind speed or intermittently in the dehumidification operation mode than in the cooling ope...
