How to choose a chiller for the injection molding machine?

Vertical and horizontal injection molding machines are used under normal ambient temperature conditions, and the cooling water condensation temperature of Jiusheng's water-cooled chiller is below 35 degrees (air-cooled chiller condensation temperature is below 43 degrees). Empirical formula: inject......

The classification and calculation method of Jiusheng chiller 　　

1. According to the type of condenser: water-cooled and air-cooled chillers 　　Water-cooled type: The chiller is connected with cooling water to take away the heat of the refrigerant in the condenser; 　　 Air-cooled type: The chiller is equipped with a cooling fan to take away the heat of the refri......

1. Jiusheng tells you the principle of chiller refrigeration: the liquid refrigerant

1. Jiusheng tells you the principle of chiller refrigeration: the liquid refrigerant (refrigerant/R22/R407C/R410A) absorbs the heat of the cooled object in the evaporator and evaporates into steam, and the compressor continuously removes the produced steam from the evaporator It is extracted and com......

What are the factors that affect the pressure of the refrigeration system?

The suction pressure is lower than normal due to insufficient cooling capacity, low cold load, low expansion valve opening, low condensing pressure (with capillary system), and filter obstruction.

Why should a refrigeration system be vacuumed? How to vacuum?

Why do refrigeration systems emphasize vacuumization? Let's take a look at the composition of the air, as shown in the figure below: Nitrogen makes up 78% of the air; Oxygen 21%; Other gases account for 1%. So let's look at, what does the composition of the gas do to the cooling system when it enter......

What are the common protections for refrigeration systems?

High pressure protection, Low pressure protection, Oil pressure protection, Anti-freezing protection, Current protection, Overheat protection, Phase sequence protection...
