Abstract
The utility model relates to the field of gas recycling, in particular to an efficient refrigerant recycler comprising a compressor, a condenser and a storage tank. The compressor, the condenser and the storage tank are connected in sequence. An inlet of the compressor is connected with a first pressure sensor. An outlet of the compressor is connected with a second pressure sensor. The first pressure sensor and the second pressure sensor are electrically connected with a frequency converter which is connected with a compressor drive motor. The efficient refrigerant recycler is stable and efficient and high in recycling speed and recycling efficiency.
Description
Technical field
The utility model relates to gas and reclaims the field, relates in particular to a kind of high efficiency refrigerant-recovery machine.
Background technology
The refrigerant-recovery machine is the equipment that reclaims the cold-producing medium in the waste air-conditioner; generally comprise a compressor, condenser and storage tank; but compressor rotary speed is single; when reclaiming beginning, it is very big to reclaim the machine inlet pressure, and overload is shut down easily; gas is recovered in the system; it is very low that snap back harvests full-time pressure, and it is very light to reclaim the machine load, causes power dissipation.Above-mentioned defective causes recovery speed very slow, and organic efficiency is low.
The utility model content
Be to solve the problem that prior art exists, the utility model provides a kind of can regulate compressor rotary speed, recovery speed is fast, efficient is high refrigerant-recovery machine according to yield.
High efficiency refrigerant-recovery machine described in the utility model, it comprises compressor, condenser and the storage tank that is connected successively, the import of described compressor is connected with first pressure sensor, the outlet of compressor is connected with second pressure sensor, described first pressure sensor and second pressure sensor are electrically connected with a frequency converter, and described frequency converter is connected with described drive motor for compressor.
High efficiency refrigerant-recovery machine described in the utility model, its beneficial effect is:
Recovery machine compressor import and export respectively connects a pressure sensor, pressure sensor connects frequency converter, when reclaiming beginning, Compressor Inlet Pressure is bigger, frequency converter checks outlet pressure sensor pressure and compressor current, when electric current when setting electric current, the frequency converter output frequency reduces automatically, compressor rotary speed is slack-off, reclaims machine stable operation.Along with the reduction of the machine of recovery inlet pressure, when frequency converter detected compressor current less than the setting electric current, the frequency converter output frequency improved automatically, and compressor rotary speed accelerates, and recovery speed accelerates.Make the efficient stable operation all the time of whole recovery process like this, thereby increase substantially recovery speed and organic efficiency.
Description of drawings
The picture that this description of drawings provides is used for assisting the further understanding to utility model, constitutes the application's a part, does not constitute to improper restriction of the present utility model, in the accompanying drawings:
Accompanying drawing 1 is the structural representation of the utility model high efficiency refrigerant-recovery machine.
The specific embodiment
To describe the utility model in detail with specific embodiment below, be used for explaining the utility model in this illustrative examples of the present utility model and explanation, but not as to restriction of the present utility model.
Embodiment:
As shown in Figure 1, high efficiency refrigerant-recovery machine described in the utility model, it comprises compressor 1, condenser 2 and the storage tank 6 that is connected successively, the import of described compressor 1 is electrically connected with first pressure sensor 4, the outlet of compressor is electrically connected with second pressure sensor 5, described first pressure sensor 4 and second pressure sensor 5 are electrically connected with a frequency converter 3, and described frequency converter 3 is electrically connected with described compressor 1.
The compressor import and export connects pressure sensor, can detect the compressor inlet and outlet pressure automatically, and frequency converter can detect the size of current of compressor, according to actual current with set current ratio, thereby regulate electric current.
When reclaiming beginning, Compressor Inlet Pressure is bigger, and frequency converter checks outlet pressure sensor pressure and compressor current, when electric current when setting electric current, the frequency converter output frequency reduces automatically, compressor rotary speed is slack-off, reclaims machine stable operation.Along with the reduction of the machine of recovery inlet pressure, when frequency converter detected compressor current less than the setting electric current, the frequency converter output frequency improved automatically, and compressor rotary speed accelerates, and recovery speed accelerates.Make the efficient stable operation all the time of whole recovery process like this, thereby increase substantially recovery speed and organic efficiency.
More than technical scheme that the utility model embodiment is provided be described in detail, this paper has used specific case principle and the embodiment of the utility model embodiment has been set forth, and the explanation of above embodiment only is applicable to the principle that helps to understand the utility model embodiment; Simultaneously, for one of ordinary skill in the art, according to the utility model embodiment, the part that on the specific embodiment and range of application, all can change, in sum, this description should not be construed as restriction of the present utility model.
