Problems solved by technology

At present, the start-up and operation control of the compressor of the dual-cooling source fresh air dehumidifier is basically divided into intervals based on the ambient temperature, and different corresponding target frequencies are set. This type of control method has a single judgment condition and fails to link the water source temperature for target frequency control, which may cause the system to start. There is a problem with running or it is slow to reach the goal set by the user
In the existing technology, the operating frequency of the compressor is corrected by the temperature of the air outlet from the evaporator, and in the case of high wind speed, high humidity and overload, the moisture content of the air outlet may not meet the user's setting requirements

Embodiment 1

[0048] figure 1 It is a flow chart of the operation control method of the dual cold source fresh air dehumidifier involved in the present invention.

[0049] like figure 1 As shown, Embodiment 1 provides an operation control method for a dual-cold-source fresh-air dehumidifier, including: turning on the fresh-air dehumidifier (dual-cold-source fresh-air dehumidifier); the dual-cold-source fresh-air dehumidifier includes two water sources and a fluorine system The cold source is used for dehumidification and cooling. In the summer cooling and dehumidification season, a cold water source is provided to enter the surface cooling section of the water coil to pre-cool and dehumidify the fresh air. The fresh air after pre-cooling and dehumidification passes through the evaporator of the fluorine refrigeration system for deep dehumidification. After two The fresh air after the dehumidification section is reduced to a comfortable air humidity; the general air conditioning system is d...

Embodiment 2

[0061] image 3 It is the principle block diagram of the operation control system of the dual cold source fresh air dehumidifier involved in the present invention.

[0062] like image 3 As shown, on the basis of Embodiment 1, Embodiment 2 also provides an operation control system for a dual-cold-source fresh air dehumidifier, including: a control module, and a detection module electrically connected to the control module; the detection The module is adapted to detect temperature and humidity data; the control module is adapted to obtain each target parameter after the fresh air dehumidifier is turned on according to the temperature and humidity data, the control module is adapted to correct the frequency of the compressor in the fresh air dehumidifier according to the corresponding target parameter, and The control module is adapted to correct the rotational speed of the fan in the fresh air dehumidifier after the compressor frequency is corrected.

Abstract

The invention belongs to the technical field of air conditioning, and specifically relates to an operation control method and a control system of a double cold source fresh air dehumidifier, wherein the operation control method of the double cold source fresh air dehumidifier includes: turning on the fresh air dehumidifier; Target parameters; correct the compressor frequency in the fresh air dehumidifier according to the corresponding target parameters; and correct the fan speed in the fresh air dehumidifier after the compressor frequency is corrected, so as to achieve a faster and more accurate adjustment to the frequency suitable for system operation and ensure system stability Reliable operation and precise control of air humidity to ensure comfortable indoor air.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to an operation control method and a control system of a dual-cold-source fresh air dehumidifier. Background technique [0002] The double cold source fresh air dehumidifier relies on the two cold sources of the water coil (pre-cooling dehumidification) and the fluorine system evaporator (deep dehumidification) to achieve the cooling and dehumidifying effect. At present, the compressor start-up operation control of the dual-cold source fresh air dehumidifier is basically divided into the ambient temperature as an interval, and different corresponding target frequencies are set. This kind of control method has a single judgment condition and fails to link the water source temperature to control the target frequency, which may cause the system to start. Problems running or slow reaching user-set goals. In the prior art, the operating frequency of the compressor i...
