Abstract
The invention discloses a method for preventing the tripping in heating start of an air conditioner. The method comprises the following steps: in the heating mode, after the compressor stops on the basis that the temperature of a compressor reaches the set temperature, the air conditioner carries out the refrigeration switching step of a four-way reversing valve, so that the air conditioner is switched to the refrigeration mode; after the refrigeration switching step of the four-way reversing valve and before the compressor is restarted, the air conditioner carries out the heating switching step of the four-way reversing valve, so that the air conditioner is switched to the heating mode. The tripping problem which is caused due to the compressor start protection caused by that the air conditioner starting current is too large is solved.
Description
Technical field
The present invention relates to a kind of method that prevents air-conditioning heating startup chaser.
Background technology
Heat pump type air conditioner has heat-production functions, four-way change-over valve is housed in air-conditioning system, the heat-production functions of air-conditioning action by four-way change-over valve is just realized, at present overseas part market due to air-conditioning without requirements such as efficiencies, therefore design is less than normal relatively for air-condition heat exchanger, air-conditioning is when heating running, the pressure at expulsion of system is relatively high, when air-conditioning in heating process, the indoor environment temperature of air-conditioning meeting automatic decision, if the temperature that environment temperature is set higher than the user, air-conditioning will stop automatically, when environment temperature returns to design temperature when following, air-conditioning can start again automatically, at this, shut down again in start-up course to temperature, because the pressure in air-conditioning system does not reach balance, can cause directly that the starting current of compressor of air conditioner is excessive, finally cause the compressor start protection, make air-conditioning cisco unity malfunction phenomenon.
Summary of the invention
The present invention mainly is to provide and a kind ofly prevents that air-conditioning heating from starting the method for chaser, makes air-conditioner before heating startup, and the pressure in air-conditioning system first reaches balance, has solved the chaser problem that the compressor start protection that causes because the starting of air conditioner electric current is excessive causes.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals: under heating mode, after compressor was shut down to temperature, air-conditioner was carried out four-way change-over valve refrigeration switch step, makes air-conditioner be switched to refrigeration mode; After four-way change-over valve refrigeration switch step, before compressor starts again, air-conditioner is carried out four-way change-over valve and is heated switch step, makes air-conditioner switch back heating mode.
As preferably, at compressor, shut down and start timing to temperature, after air-conditioner elapsed time T1, then carry out described four-way change-over valve refrigeration switch step.
As preferably, after described four-way change-over valve refrigeration switch step, after air-conditioner elapsed time T2, then carry out described four-way change-over valve and heat switch step.
As preferably, after described four-way change-over valve heated switch step, after air-conditioner elapsed time T3, compressor restarted again.
As preferably, described condition of shutting down to temperature comprises: environment temperature TA is greater than design temperature TS.
As preferably, described T1 is 100 seconds, and T2 is 10 seconds, and T3 is 10 seconds.
As preferably, after described compressor is shut down to temperature, repeatedly carry out described four-way change-over valve refrigeration switch step and described four-way change-over valve refrigeration switch step.Air-conditioner stops at compressor, under the unbalanced state of system pressure; carry out continually the switching of refrigeration mode and heating mode; can reduce like this pulse produced due to the moment connection of pattern switching high-low pressure pipeline; effectively protect pipeline and the parts of system, reduced the generation of noise.
As preferably, be less than 1S the interval time between described four-way change-over valve refrigeration switch step and described four-way change-over valve refrigeration switch step.
The beneficial effect that the present invention brings is, the present invention is by the switching of four-way change-over valve, make system pressure obtain rapid balance, prevented the chaser problem when compressor is restarted, having the present invention to pass through four-way change-over valve switches repeatedly again, not only reach pressure balanced purpose, also avoided on the other hand the impact to system pipeline and parts, reduced the generation of noise.
The accompanying drawing explanation
Accompanying drawing 1 is a kind of structural representation of air-conditioning system of the present invention.
Label declaration: 1, four-way change-over valve; 2, evaporimeter; 3, condenser; 4, compressor; 5, pipeline.
The specific embodiment
Below by embodiment, and by reference to the accompanying drawings, technical scheme of the present invention is described in further detail.
Embodiment 1: the present embodiment a kind of prevents method that air-conditioning heating starts chaser as shown in Figure 1, and air-conditioning system is comprised of controller, four-way change-over valve 1, evaporimeter 2, condenser 3, compressor 4 and pipeline 5.
During the air-conditioning heating operation, refrigerant is discharged by compressor 4, by four-way change-over valve 1 commutation, arrive evaporimeter 2, by after evaporimeter 2 condensations, reaching condenser 3, after condenser 3 evaporations are arranged, return compressor 4 through four-way change-over valve 1, formally continuous circulation realizes in air-conditioning system by above-mentioned said refrigerant in air-conditioning heating work.
The a kind of of the present embodiment prevents that the method for air-conditioning heating startup chaser is as follows:
Under heating mode, when environment temperature TA is greater than design temperature TS, compressor 4 is shut down, and timer is shut down from compressor 4 to temperature and started timing, after 100S, air-conditioner is carried out four-way change-over valve 1 refrigeration switch step, by the switching of four-way change-over valve 1, make air-conditioner be switched to refrigeration mode, now high-low pressure pipeline 5 moments connection, pipeline is equivalent to short circuit, can guarantee like this to guarantee the high-low pressure balance within 10 seconds;
After 10S, air-conditioner is carried out four-way change-over valve and is heated switch step, makes air-conditioner switch back heating mode;
After 10S, compressor 4 restarts again.
Embodiment 2: the present embodiment a kind of prevents that method that air-conditioning heating starts chaser as shown in Figure 1, under heating mode, when environment temperature TA is greater than design temperature TS, compressor 4 is shut down, timer is shut down from compressor 4 to temperature and is started timing, after 100S, air-conditioner is carried out four-way change-over valve 1 refrigeration switch step, switching by four-way change-over valve 1, make air-conditioner be switched to refrigeration mode, after 1S, air-conditioner is carried out four-way change-over valve and is heated switch step, make air-conditioner switch back heating mode, pass through again 1S, air-conditioner is carried out four-way change-over valve 1 refrigeration switch step again, so repeatedly carry out four-way change-over valve 1 refrigeration switch step and four-way change-over valve and heat switch step for several times, the several of two kinds of patterns, after 13S, air-conditioner is carried out last four-way change-over valve and is heated switch step, and start simultaneously compressor 4.The other technologies feature is identical with embodiment 1.
Below only with regard to preferred embodiment of the present invention, be described, but can not be interpreted as it is limiting the scope of the invention.The present invention not only is confined to above embodiment, and its concrete structure or shape allow to change.In a word, protection scope of the present invention should comprise those apparent conversion or alternative and remodeling to those skilled in the art.
