Abstract
The invention discloses an electricity auxiliary heating control method of an air conditioner. The step of closing electricity auxiliary heating comprises an intelligent energy saving turning-off condition: when a heating mode operates and the electricity auxiliary heating is turned on, the heating mode operates for certain times; when the difference of practical room temperature and set temperature is less than delta t and the operation frequency of a compressor is not the maximal frequency, the electricity auxiliary heating is turned off, and the operation frequency of the compressor is improved by N%; if the operation frequency exceeds the highest frequency set by the compressor, the compressor operates according to the highest frequency. The invention can lower the power consumption of a user as much as possible to achieve the purpose of energy saving while ensuring the heating capacity of the air conditioner.
Description
Technical field
The present invention relates to air-conditioning control field, the particularly electricity auxiliary heating control method of controllable rotation speed cold-warm type domestic air conditioner.
Background technology
Pump type heat (cold-warm type) domestic air conditioner, its heating capacity descends under worst cold case, in order to improve its heating capacity, has generally increased electric auxiliary heating in air-conditioner.But the auxiliary heating of electricity power consumption is bigger, and the auxiliary efficiency of heating surface of electricity is much smaller than the heating efficiency (Energy Efficiency Ratio) of refrigeration system.
Present electricity is auxiliary to be added in the thermal control, and following several scheme is arranged.A kind of automatically controlled control that is pure by air-conditioner, preestablish the unlatching of the auxilliary heat of electricity must condition with close necessary and sufficient condition, the user can not intervene.The hommization of this a kind of scheme is bad, but fairly simple.Second kind of control mode has automatically and manual two kinds, and promptly the user can select to allow the auxiliary heating of electricity open, close or allow the auxiliary heating of electricity open automatically, close according to actual conditions.As shown in Figure 1, the auxiliary heating of electricity be opened and seven condition steps will be satisfied simultaneously:
(1) judges whether to be in and heat operation mode,, if not, then return if then carry out next step;
(2) judge that whether the auxilliary heating function of PTC electricity is opened, if then carry out next step, if not, then returns step (1);
(3) judge whether compressor is opened,, if not, then return step (1) if then carry out next step;
(4) judge the time more than 1 second is opened and opened continuously to indoor fan whether,, if not, then return step (1) if then carry out next step;
(5) judge that whether evaporator temperature T2 is not higher than T4 (the preferential scope of T4 is 45-60 ℃), if then carry out next step, if not, then returns step (1);
(6) judge whether in non-defrost or the non-defrost tenth skill,, if not, then return step (1) if then carry out next step;
(7) judge whether indoor environment temperature T1 is not higher than T3 (the preferential scope of T3 is 20-30 ℃),, if not, then return step (1) if then open the auxiliary heating of electricity.
As shown in Figure 2, open under the operation, close the auxiliary heating of electricity and only need not satisfy above-mentioned seven unlocking conditions any one gets final product in the auxiliary heating of electricity.
This a kind of control mode is the comparison hommization, but, in the controllable rotation speed room air conditioner, because the rotating speed of compressor can be transferred, in the design in the past, do not consider the control of compressor rotary speed to the auxiliary heating of electricity, after user's start heats a period of time, room temperature rises, compressor rotary speed descends, but the auxiliary heating of electricity unlatching always, because the efficiency of the auxiliary heating of electricity is far below the heating efficiency of heat pump, still open the auxiliary heating of electricity after reaching requirement heating, cause whole heating efficiency lower.
Summary of the invention
The objective of the invention is to overcome the deficiency of existing product technology, design a kind of transducer air conditioning electricity auxiliary heating control method, when guaranteeing heating capacity of air conditioner, can reduce user's power consumption again as far as possible, reach purpose of energy saving.
To achieve these goals, technical scheme of the present invention is: a kind of electricity auxiliary heating control method of air conditioner comprises:
(1) is used to open the auxiliary step that heats of electricity, comprise and must satisfy seven steps just can opening the auxiliary heating of electricity simultaneously: heating mode operation, the auxilliary heating function of electricity for open, compressor leaves, indoor fan is held and open X above time of second, evaporator temperature T2 continuously is not higher than in certain value T4, non-defrost or the non-defrost tenth skill that (the blower fan unlatching can be blown a cold wind over during defrost, be unfavorable for the user, so blower fan can not be opened during defrost), indoor environment temperature T1 is not higher than certain value T3;
(2) be used to close the step of the auxiliary heating of electricity, comprise and only need satisfy the step that one of them can close the auxiliary heating of electricity: non-heating mode operation, the auxilliary heating function of electricity are higher than in continuous a period of time for closing, compress office, indoor fan pass, evaporator temperature that step and indoor environment temperature are higher than T3 in continuous a period of time in T4, the defrost process;
The described auxiliary heating steps of electricity of closing comprises that also intelligent power saving closes condition: under the situation that heating mode running and the auxiliary heating of electricity are opened, operation a period of time, the actual temperature in room and set temperature value difference are less than Δ t, and when the frequency of compressor operating is not peak frequency, close the auxiliary heating of electricity, simultaneously the operating frequency of compressor is improved N%, the highest frequency that surpasses the compressor setting is then pressed the highest frequency operation.
As a kind of preferred version, the described intelligent power saving condition of closing is to be used to close the abundant inessential condition that electricity is assisted the step of heating, even if the discontented condition that is enough to be used to close the auxiliary step that heats of electricity, electric miscellaneous function can realize closing too.
As further preferred version, described Δ t is 0-5 ℃.
As further preferred version, N% is 1%-20%.
As further preferred version, described T4 is 50-60 ℃, and T3 is 20-35 ℃.
Compared with prior art, electricity auxiliary heating control method of air conditioner of the present invention meets the requirements of under the prerequisite heating, and closes the auxiliary heating of the lower electricity of electrical efficiency, adopts the higher heat pump of Energy Efficiency Ratio to heat; Close the auxiliary heating of electricity after reaching requirement heating, improve whole heating efficiency, reach purpose of energy saving.
