Energy-saving Air Conditioner
Taking a 1000 square meter workshop as an example, a comparison of investment and usage costs for various types of air conditioners.
1.choose the tranditional split AC: 13 sets 5hp AC, Cost around 20,000usd,Total power:48kw,Each air conditioner is independently controlled, with a small coverage area, slow heat transfer speed, and low efficiency.
2.Choose the central air conditioner: 1 sets 60hp air cold chiller,Cost arond 40,000usd,Total power:45kw,The cooling effect is good, but the investment and use costs are high because it cannot be controlled independently.
3.Choose the power saving air conditioner 5 sets 5hp power saving air conditioner, Cost around 15,000usd,Total power:20kw,Good cooling effect, fast heat exchange speed, large coverage area, independent control, low investment and use costs. Mian spare parts Disadvantages: It has requirements on water quality.
Energy-saving Air Conditioner
Operational principle
Through a combination of water cooling, air cooling, and compressor working methods, the external unit first uses wet curtain evaporative condensation technology to cool the circulating water. After the water temperature drops to room temperature, it flows through the heat exchange system of the internal unit (at this time, the compressor has already operated and compressed the refrigerant into a high temperature and high pressure state), taking away most of the heat of the high temperature refrigerant to form a room temperature refrigerant. The room temperature refrigerant then passes through a throttle valve and becomes a low temperature and low pressure refrigerant, which is transported to the evaporator in the upper part of the internal unit to blow out cold air. The circulating water that has cooled the high temperature and high pressure refrigerant is then transported to the upper part of the outdoor unit by a water pump. At the same time, with the assistance of air cooling, it flows through the evaporative water curtain to turn the high temperature water into normal temperature water, which then flows through the indoor unit again The cooling of refrigerant under high temperature and high pressure, and the cyclic operation will maximize the energy efficiency 03 ratio, So as to reduce energy consumption.
Component Parts
The evaporative energy-saving air conditioning unit consists of a compressor, condenser, expansion valve, evaporator, wet curtain, water tank, water pump and other parts.
