Brief introduction:
1. Unit Introduction:
*Compressor
High-efficiency scroll compressor with low noise and long life.
*Evaporator
Shell and tube evaporator, high-efficiency internally threaded copper tube, with low flow resistance and high efficiency.
* Condenser
High-efficiency internally threaded copper tubes and high-quality hydrophilic aluminum coil fins, excellent production.
Secondary stamping and flanging technology, double corrugated sheet design, and mechanical tube expansion processing ensure that the copper tube and aluminum fins are tightly combined to obtain the best heat exchange effect.
* Distribution control box
The microcomputer controller adopts a well-known brand and can operate stably and reliably at an ambient temperature of -15 ° C to 55 ° C.
* Imported accessories
Selected refrigeration accessories of well-known brands are stable and reliable.
*Safety Facilities
High and low pressure switch, antifreeze protection, oil heating belt, drying filter, overload protector, power protector.
2. Heat Recovery Type Modular Type Air Cooled Water Chiller And Heat pump (non-standard unit, please indicate when ordering)
a> Heat recovery unit is one unit that integrates two or three functions of refrigeration, heating and making domestic hot water. There are two types of heat recovery: 30% recovery and 100% recovery.
b> The cooling only unit can recover the originally discarded condensing heat while cooling in summer, and can also be cooled separately; the heat pump unit has three functions of cooling, heating and making domestic hot water.
c> The comprehensive performance coefficient of the heat recovery unit is as high as 3.5 ~ 3.9. The addition of the heat recovery unit is equivalent to increasing the heat exchange area of the unit and enhancing the heat exchange effect, thereby reducing the energy consumption of the unit.
3. Low Temperature Modular Type Air Cooled Water Chiller And Heat pump (non-standard unit, please specify when ordering)
Adopting EVI scroll compressor and economizer, the unit can be used normally in low temperature environment, and greatly improve the heating operation efficiency of the unit in winter.
a> The compressor has added one gas filling port, the suction air of the unit is increased, the circulation flow is increased, the heat exchange heat of the unit on the condensing side is greatly increased, the heating capacity of the unit is increased by more than 30%, and the performance coefficient Also greatly improved.
b> By optimizing the matching of products, the amount of refrigerant evaporated in the evaporator at low ambient temperature is increased, which can effectively avoid the failure of the refrigerant to completely evaporate due to the poor evaporation effect and the return of the compressor.
c> Increase the enthalpy of the compressor by supplementing the air, increasing the displacement of the compressor, ensuring that the product still runs stably at low ambient temperature, the compressor will not exceed the compression ratio of the compressor, ensuring the safe performance of the compressor Reduce the compressor discharge temperature and extend the life of the compressor.
