Abstract
The invention discloses a control method of operating modes of an air conditioner, which comprises the following steps of realization: judging whether the air conditioner is under manual mode controlor automatic mode control; if the air conditioner is under the manual mode control, according to a manual mode control program, judging whether a user selects an air supply mode or not; if the user selects the air supply mode, converting to a manual mode conversion searching table for correspondingly carrying out the air supply mode; if the user does not select the air supply mode, firstly, balancing the internal pressure of an air conditioning system, and then, according to a refrigeration or heating or dehumidification mode selected by the user, converting to the manual mode conversion searching table for correspondingly carrying out the refrigeration or heating or dehumidification mode; and if the air conditioner is under the automatic mode control, converting to an automatic mode control program for carrying out the automatic mode. The control method of the operating modes of the air conditioner can realize five control modes of refrigeration, heating, air supply, dehumidificationat constant temperature, dehumidification at increased temperature and dehumidification at reduced temperature, and can realize the conversion of the functions under the two control methods of the manual mode and the automatic mode. In addition, under the dehumidification control mode, the automatic conversion of the three modes of constant temperature, temperature reduction and temperature increase can be realized.
Description
Technical field
The present invention relates to room air conditioner, be specifically related to improvement the operating modes of air conditioner control method.
Background technology
Existing room air conditioner, generally by compressor, capillary, four-way change-over valve, parts such as outdoor heat exchanger and indoor heat exchanger are formed, and these three kinds of operational modes comprise refrigeration, heat and blow.Generally speaking, the operational mode of existing room air conditioner is (being that air-conditioner is to work under artificial control model) that is set up on their own by the user according to user's needs, can not change automatically between above-mentioned three kinds of operational modes, for example air-conditioning is when the running refrigerating pattern, can not be automatically changeb to heating mode according to the needs of room temperature; Same, if air-conditioning is moving heating mode, it also can't be transformed into air supply pattern etc. automatically according to the needs of room temperature.
Traditional room air conditioner heats and the mode of operation of blowing is not possess dehumidification function, only just can realize the cool-down dehumidification function when refrigerating operaton.In addition, traditional room air conditioner, the cool-down dehumidification function also is subjected to the influence of environment temperature, has only environment temperature when spending greater than 16, just can realize the cool-down dehumidification function.Therefore, adopt traditional room air conditioner to be used as the dehumidifier equipment of producing tealeaves, shortcoming is quite obvious, and it not only can be subjected to the influence of environment for use, nor can satisfy the needs that can dehumidify various seasons.
Summary of the invention
The present invention provides technical problem to be solved and provides a kind of operating modes of air conditioner control method, it can freeze in fact, heat, air-supply, constant temperature dehumidification, intensification dehumidifying and cool-down dehumidification control, and realizes that these several functions are changing under artificial pattern and two kinds of control modes of automatic mode.
For solving the problems of the technologies described above, the control method of this operating modes of air conditioner is: the assembly work by central control unit control air-conditioner realizes, the assembly of air-conditioner includes compressor, outdoor heat exchanger, indoor heat exchanger and be configured in compressor and outdoor, switch the cross valve of coolant path between the indoor heat exchanger, described indoor heat exchanger includes indoor first heat exchanger and indoor second heat exchanger, be connected with the first magnetic valve throttle part between indoor first heat exchanger and the outdoor heat exchanger, be connected with the second magnetic valve throttle part between indoor first heat exchanger and indoor second heat exchanger, the described first magnetic valve throttle part is connected in parallel by first magnetic valve and first throttle parts and forms, the second magnetic valve throttle part is connected in parallel by second magnetic valve and second throttle part and forms
Wherein, the control method of operating modes of air conditioner may further comprise the steps:
(1), judge that air-conditioner is in artificial pattern or automatic mode control,
(2) if artificial pattern is controlled, then undertaken by artificial model program:
(3) if automatic mode control then enters automatic mode control subprogram and carries out.
Artificial model program in the such scheme comprises the steps:
Whether what judge at first that the user selects is air supply pattern, if then turn to the corresponding air supply pattern of carrying out of artificial pattern conversion and control question blank; If not air supply pattern, then compressor shutdown was restarted operation after 3 minutes, the outdoor fan operation, and the operation of air conditioner pattern of selecting according to the user redirect to corresponding execution the in the artificial pattern conversion and control question blank then;
Automatic mode control subprogram in the such scheme comprises following steps:
Be in refrigeration mode as air-conditioner, then carry out the control scheme of refrigeration mode;
Be in heating mode as air-conditioner, then carry out the control scheme of heating mode;
Be in dehumidification mode as air-conditioner, then forward automatic dehumidification mode conversion query table to and carry out; Automatically under the dehumidification mode, central control unit is selected to carry out cool-down dehumidification, constant temperature dehumidification and is heated up dehumidifying control scheme according to the temperature difference between indoor air temperature and the user's design temperature.
The present invention has following remarkable result compared to existing technology:
Operating modes of air conditioner control method of the present invention can realize freezing, heats, air-supply, constant temperature dehumidification, intensification dehumidifying and five kinds of control models of cool-down dehumidification control, and realizes the conversion of these several functions under artificial pattern and two kinds of control modes of automatic mode.In addition, under the dehumidifying control model, can also realize the automatic conversion between constant temperature, cooling and three kinds of patterns of intensification.
