(Activities of cold storage, also known as prefabricated cold storage, assembly-type cold storage, modular cold storage) energy-saving activities in cold condensation machine application of energy-saving
"Energy saving" in Active cold Bowen on the practical application of the analysis: first, the "energy-saving Bao" is an AC induction motor controller: it can under activity cold condensation machine motor of different load adjustment motor power actually needed. Normally, the motors in the long running time loaded with no-load, saving precious time and motor operation status, by chip control technology for automatic detection of adjustment, the motor running less power consumption. 2. Why is the "energy-saving activities Po" can reduce the power consumption of refrigeration compressors: first of all, we understand the activities characteristic of the condenser working cold storage and refrigeration gas characteristics:
Condensing gas characteristics:
Refrigerants such as a regular flow of fluids, with increased temperature and pressure changes. When the refrigerant in the refrigeration, in the high pressure (9bar) 38 degrees Celsius, it will change the State from gas to liquid. When the evaporator heat, smaller pressure (1.5bar) minus 20 degrees Celsius, it from liquid into gas. Activities in the refrigeration systems of four basic components:
1. compressor: the gas refrigerant compression.
2. refrigerant condenser: order status changes from gas to liquid.
3. the expansion valve: the refrigerant (liquid), pressure drop sharply, causing cooling the refrigerant.
4. evaporator: for cooling purposes. Activities in the refrigeration cycle to MU Rui Lin displayed the table, this table lists the refrigeration cycle pressure and enthalpy (total calories) in point 1 and point 2: gas refrigerants in constant enthalpy of compression. In fact, the entire compression program will make the temperature rise, so the real amount is compared to the theory of enthalpy.
In point 2 and points 3: gas refrigerant at constant pressure cooling, direct cooling with refrigerant by half.
In point 3 to point 4: through the expansion valve, the amount of refrigerant in constant enthalpy inflated.
In point 4 to point 5: refrigerant to the evaporator inside constant pressure by evaporation. Activities-saving refrigerator installation "Po" after effects: activities-saving refrigerator installed "Po", the entire refrigeration cycle will be at a lower volume and pressure for enthalpy. In point 1 and point 2: when you configure a "power saving", the activities of the refrigerator, electrical work in less time, energy and waste reduction. When air enters the cylinder is only less heat, more air you can gather, the pump every time compression more effective.
In point 2 and points 3: active cold condensation of condenser range is not changed in the condenser outlet only less liquid heat cannot absorb, in point 2 will have less pressure and temperature.
In point 3 to point 4: when the refrigerant through the expansion valve, the pressure started to drop to the lowest point. Temperature with pressure drop to the saturation temperature.
In point 4 to point 1: refrigerant temperature lower than before the installation, when entering the activity when the cold storage evaporator heat lessons faster than before, the working time is shorter. Why is the "energy-saving activities Po" can reduce the power consumption of refrigeration compressors: 1) because the activities of the motor and compressor refrigerator compressor are placed in a sealed box, HP gas became a closed gas circuit, and the gas must be validated before the next motor can reach gas cylinders, motors work the heat is delivered directly to the cooling of gases, the temperature rise. When the device after the power-saving Po, active cold condensation machine motor temperature significantly lower their work distributed heat less, so the gas is cooling, does not affect too many of its temperature rises, so the active cold condensation machine cooling effect is better.
2) activities to its built-in refrigerator thermostat adjustable cooling system for operation, because "save power Po" reduces the motor operating temperature, the compressor can take less time to refrigerator temperature drop.
