Abstract: The present disclosure provides a control method, apparatus, and device for a compressor, a storage medium, and a refrigerator system. The control method includes: obtaining an electrical parameter, a return air parameter, and a first frequency of the compressor during operation of the compressor; determining a first fitting formula corresponding to the first frequency; obtaining an exhaust pressure by inputting the electrical parameter and the return air parameter into the first fitting formula for calculation; and controlling the compressor based on the exhaust pressure. In this way, the pressure sensor disposed on an exhaust side of an air conditioner can be omitted, hence cost is saved; or for the air conditioner with the pressure sensor on the exhaust side, the above manner for calculation can be an alternative to obtaining the exhaust pressure, which ensures a user's normal use and thus improves the user experience.

Abstract: Agglomerates of water insoluble builder molecular sieve zeolites are made by tumbling or otherwise suitably mixing very finely divided ion exchanging zeolite powder and a water soluble binder, such as starch, preferably in the presence of a small amount of moisture sufficient to promote desirable agglomeration of the finely divided ion exchanging zeolite particles and the binder into essentially spherical particles, preferably in the 6 to 140 mesh range. The agglomerates are readily disintegrated when agitated in water and rapidly release the separated very finely divided insoluble builder particles to allow them to remove hardness ions from the water. The dispersible and disintegrable agglomerates are especially useful in heavy duty detergent compositions wherein the zeolite of the agglomerate provides all or a substantial proportion of the builder content.
