Abstract
The utility model provides an air conditioning control system with a function of preheating a compressor. The air conditioning control system comprises a main control unit, a temperature detecting unit, a display unit, a power supply unit, an air conditioning output unit and a heating device for preheating the compressor, wherein the temperature detecting unit, the display unit, the power supply unit, the air conditioning output unit and the heating device are connected with the main control unit in a one-to-one correspondence mode respectively, meanwhile the power supply unit is connected with the air conditioning output unit, and the heating device is connected onto an electric control board of an air conditioning indoor unit. According to the scheme of the air conditioning control system with the function of preheating the compressor, the compressor can be preheated when an air conditioner is utilized in the low temperature environment, the compressor can be effectively run in a good compressor oil lubrication state, and compressor damage caused by mechanical abrasion is reduced.
Description
Technical field
The utility model relates to the technical field of air-conditioner, refers in particular to a kind of air conditioner control system with compressor preheating function.
Background technology
At present, electrical heating has applied to daily family field, and also application is very extensive in air-conditioner, but should protect this field still blank in compressor preheating.Be directed to some low temp areas and use air-conditioner, because thereby compressor oil active decline under low temperature condition can not be played the effectively lubricating effect to compressor cylinder, moving component and air bleeding valve, thereby the mechanical wear that causes obviously increases, thereby makes compressor damage cause maintenance cost to increase.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of air conditioner control system with compressor preheating function is provided, guarantee that effectively compressor being carried out preheating under low temperature condition guarantees that compressor turns round under good lubricating status, reduce the mechanical wear of compressor moving component, thereby prolong the life-span of compressor, reduce the maintenance cost of air-conditioner.
For achieving the above object, technical scheme provided by the utility model is: a kind of air conditioner control system with compressor preheating function, it includes main control unit, temperature detecting unit, display unit, power subsystem, air-conditioning output unit and the heater that carries out preheating for compressor, wherein, described temperature detecting unit, display unit, power subsystem, the air-conditioning output unit, heater respectively with main control unit corresponding joining one by one, simultaneously, this power subsystem is connected with the air-conditioning output unit, and this heater is connected on the automatically controlled plate of air conditioner room unit.
Described heater is the bent axle heating tape, and this bent axle heating tape is wrapped in compressor surface, and is close to compressor by spring.
Described display unit includes interconnective display module and display driver chip, and wherein, this display driver chip joins with DA pin, CLR pin, the STB pin of main control unit respectively.
Described air-conditioning output unit includes interconnective drive circuit and air-conditioning output module.
The utility model uses air-conditioner under low temperature environment after having adopted such scheme, can carry out preheating to compressor, guarantees that effectively compressor moves under the state of good compression oil lubricating, reduces the compressor damage that causes because of mechanical wear.
