Description
Technical field
The invention belongs to the air-conditioner technical field, relate in particular to a kind of standby electric heating control device and method of air-conditioner.
Background technology
When air-conditioner was lower than-10 ℃ of heating operations in outdoor temperature, because outdoor temperature is low excessively, the liquid refrigerants that is stranded in the compressor was too much, when causing compressor start, does not start because of liquid hammer occurring.Therefore, the air-conditioner that uses under low temperature environment at present generally all can be provided with tens watts heat tape in the compressor bottom, and heat tape is in heated condition all the time under holding state, and compressor just can normally start operation when the start operation.
Because heat tape is in heated state for a long time, has consumed a large amount of electric power.But, for air-conditioner can normally start and must heat, so, waste for fear of electric power, at present indivedual producers' employings dozens of minutes before heating operation is opened heat tape earlier, brought inconvenience in the extreme but for user's use, therefore, most of producers still adopt the mode of the long-term heating of standby.
Summary of the invention
At the shortcoming of prior art, the purpose of this invention is to provide a kind of standby electric heating control device and control method of reaching effectively energy-conservation air-conditioner heat time heating time that shortens the compressor heater significantly.
For achieving the above object, technical scheme of the present invention is: a kind of standby electric heating control device of air-conditioner, it comprises control system and first temperature sensor that is used for the outer machine heat exchanger temperature of nernst cell that is connected with control system, second temperature sensor that is used for induced compression motor spindle temperature, gives the heater of compressor bottom heating, and control system is according to the duty of the signal comparative result control heater of first temperature sensor and second temperature sensor.
This control system also comprises timing control module, and it is used for the duty of timing controlled heater.
This control system also comprises the information storage module that is connected with timing control module, is used to store the pairing timing controlled parameter in various places, and timing control module is called corresponding timing controlled parameter according to the location.
This heater is a heat tape.
The present invention also provides a kind of standby electric heating controlling method of air-conditioner, and it may further comprise the steps:
(1) one first temperature sensor is set on the off-premises station heat exchanger, one second temperature sensor is set, one heater is set in the compressor bottom in the compressor bottom;
(2) in air-conditioner standby process, by machine heat exchanger temperature and compressor bottom temp outside first, second temperature sensor difference sensing chamber, control system is according to the duty of the comparative result control heater of off-premises station heat exchange temperature and compressor bottom temp, if the off-premises station heat exchange temperature is lower than the compressor bottom temp, then close heater; On the contrary, if the off-premises station heat exchange temperature is higher than the compressor bottom temp, then open heater.
This control system also comprises timing control module, and it is used for the duty of timing controlled heater.
Control system also comprises the information storage module that is connected with timing control module, is used to store the pairing timing controlled parameter in various places, and timing control module is called corresponding timing controlled parameter according to the location, and by timing controlled parameter control heater.
Compared with prior art, the present invention has following advantage:
The present invention is by the duty of control system according to the signal comparative result control heater of first temperature sensor and second temperature sensor, the heating of only when compressor need heat, just switching on, shorten the heat time heating time of compressor heater significantly, thereby effectively reach purpose of energy saving.
Combine timing control module in addition, can effectively avoid owing to turn-off the too high damage that brings to device of frequency.
Description of drawings
Fig. 1 is a theory structure block diagram of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described in detail.
As shown in Figure 1, the invention discloses a kind of standby electric heating control device of air-conditioner, it comprises that control system reaches the machine heat exchanger temperature outside the nernst cell that is used for that is connected with control system, be outdoor environment temperature first temperature sensor, be used for induced compression motor spindle temperature second temperature sensor, give the heater of compressor bottom heating, control system is controlled the duty of heater according to the signal comparative result of first temperature sensor and second temperature sensor.In the present embodiment, this heater is a heat tape.
This installs the heating of only just switching on when compressor need heat, shorten the heat time heating time of compressor heater significantly, thereby effectively reach purpose of energy saving.
In one day 24 hours, because the influence of radiator, in the different periods, compressor temperature and outdoor environment temperature are not identical.Generally 6 of mornings are between at 6 in afternoon, because the heat exchange efficiency of heat exchanger is higher than compressor far away, therefore, heat exchanger remains with environment temperature basic identical, compressor temperature then is lower than ambient air temperature, cold-producing medium flows to compressor according to hanging down the principle that flows by the temperature height to temperature, and just must open electrical heating brings heating to this period compressor start.6 to just in time opposite between 6 of mornings at night, because environment temperature reduces gradually, the temperature that the temperature of compressor underspeeds less than heat exchanger underspeeds, therefore, the temperature of compressor is higher than heat exchange temperature, the refrigerant flow direction heat exchanger, do not need to open electrical heating and bring heating this moment.
For this reason, this control system also comprises timing control module, and it is used for the duty of timing controlled heater.So, just can avoid in the morning at 6, can effectively avoid owing to turn-off the too high damage that brings to device of frequency to the defective that often needs the control heat tape to turn-off between at 6 in afternoon.
Yet have some difference between country variant, the different regions, period need be done suitable adjustment, the user uses operation for convenience, this control system also further comprises the information storage module that is connected with timing control module, be used to store the pairing timing controlled parameter in various places, timing control module is called corresponding timing controlled parameter according to the location.So, only need weather and ground domain information entry information memory module, and change into the timing controlled parameter, just can conveniently set flexibly, improved popularity and the convenience used greatly timing control module by this information storage module with various places.
In addition, the invention also discloses a kind of standby electric heating controlling method of air-conditioner, it may further comprise the steps:
(1) one first temperature sensor is set on the off-premises station heat exchanger, one second temperature sensor is set, one heater is set in the compressor bottom in the compressor bottom;
(2) in air-conditioner standby process, by machine heat exchanger temperature and compressor bottom temp outside first, second temperature sensor difference sensing chamber, control system is according to the duty of the comparative result control heater of off-premises station heat exchange temperature and compressor bottom temp, if the off-premises station heat exchange temperature is lower than the compressor bottom temp, then close heater; On the contrary, if the off-premises station heat exchange temperature is higher than the compressor bottom temp, then open heater.
