Note: Due to the large difference in heat dissipation of the unit, the specific parameters will vary depending on the design system and the selected accessories; each power refers to the average value after the unit is stable; the heat recovery energy utilization refers to the recovered energy of "sanitary hot water + heating or cooling" Sum.
The cooling, heating and power system adopts different waste heat recovery methods according to the principles of economy and energy. The main parts of the absorption chiller used are as follows:
Product advantages:
System advantages and composition
The integrated cooling, heating and power unit realizes the cascade utilization of energy through the deep recovery of the waste heat of the internal combustion engine, and the energy utilization efficiency can be increased from 35% for simple power generation to more than 85% for combined cooling, heating and power.
Exquisite workmanship and strict quality inspection
The unit has passed fine workmanship to ensure the reliability of product processing; passed the five-process quality inspection, and the national standard test bench is strictly debugged to ensure that each factory unit has reliable performance.
Reliable and flexible electrical control system
The company uses first-line brand control components to ensure the reliability of the control system hardware.

Our company has further improved the COP of products through self-developed and optimized control procedures. The control system has protection functions such as water shortage protection, high temperature alarm, and automatic shutdown of faults. According to the needs of users, our company can individually design the control system to meet the various needs of users.
Simple and convenient operating system
The user can switch on and off with one key, and can also choose time switch, temperature control switch and other methods to control the start and stop of the unit, which increases the convenience of operation for customers. The unit's touch screen displays real-time operating data, and users can also collect unit operating data through remote monitoring.
Flexible use place
The heating and cooling generators are suitable for large hotels, biogas power stations, ports, construction sites and other places. In addition to the stand-alone power generation, the unit can also be integrated into the municipal power grid (the grid-connected mode is optional), and the reliability of power supply is greatly improved. In addition, the generator set can cooperate with our company's vacuum hot water unit, single and double-effect refrigeration unit and other equipment to realize different forms of cogeneration systems such as combined heat and power, combined cold and power.
