How electric heaters, heat sources, and heat pumps work under different operating conditions

How electric heaters, heat sources, and heat pumps work under different operating conditions

1, Low temperature working condition of electric heater

Electric heaters are used in cold areas with low outdoor heating calculation temperatures. The evaporation temperature of the air source heat pump is inevitably low, and the compressor working at high compression ratios will inevitably lead to a decrease in the volumetric efficiency and indicated efficiency of the compressor. In this way, the heating capacity and coefficient of heating performance of the high-temperature fan heat pump will decrease. A better method is to add auxiliary heat source equipment, and an electric heater is an ideal auxiliary heat source equipment.

2, Electric heaters do not require auxiliary equipment

The air source heat pump of the electric heater does not require any other auxiliary equipment and has obvious advantages in installation, operation, and maintenance compared to other equipment such as small boilers.

3, Installation of electric heater, heat source, and heat pump

After installation, the electric heater is integrated with the central air conditioning unit, and when in use, it can achieve linkage control with the unit, pre heating the circulating water, increasing the water temperature, ensuring the normal start and operation of the air conditioning unit, and improving the heating efficiency and effect of the air conditioning unit.

4, Electric heater, heat source, heat pump power consumption

The power consumption of the air source heat pump of the electric heater can be compensated by improving the efficiency of the central air conditioning unit during heating operation, and the total power consumption does not increase significantly.

The use of electric heaters for heat treatment purposes

The heat treatment purpose of electric heaters can be used for local or overall quenching, annealing, tempering, and heat permeation of various metals; The hot forming application range of electric heaters includes whole piece forging, local forging, hot heading, and hot rolling; Electric heaters can be used for brazing various metal products, welding various cutting tools and saw blades, welding steel pipes and copper pipes, and welding of the same and different metals; Used for (vacuum) melting, casting and evaporative coating of metals such as gold, silver, copper, iron, aluminum, etc; Electric heaters can also be used for high-frequency heating machines and other semiconductor single crystal growth, heat matching, bottle mouth heat sealing, toothpaste skin heat sealing, powder coating, and the manufacturing of metal implanted plastics. Electric heater is a popular electric heating equipment in today's society.

The steps for calculating the power of an electric heater: Draw a heating process flowchart based on the process flow (without involving material form and specifications). Calculate the heat required for the electric heater process, calculate the heat and time required for system startup. Redraw the heating process flowchart, consider appropriate safety factors, and determine the total power of the heater. Determine the sheath material and power density of the heating element of the electric heater. Determine the form, size, quantity, and power supply and control system of the electric heater.
