High temperature multi-stage heating water chiller and heater

Cooling Capacity (kW): 122.1~1800
Heating Capacity (kW): 162.5~2169.7
EER: 3.02~3.88(cooling) 4.02~4.98(heating)
1. High temperature multi-stage heating water chiller and heater creatively uses the advanced technology of significant latent heat separation and recovery, energy cascade utilization,  the use of condensing heat generated by air conditioning cooling operation will be 100% recycled and gradual heating domestic hot water, truly achieve super energy saving. It can directly obtain domestic hot water of 60℃ while meet the requirements of cooling capacity, no other heat source auxiliary heating. EER can be up to 8.5 or more.

2. Designed four energy-saving operation modes: Four energy-saving operation modes include business single effect cooling, business single effect heating, business double effect cooling and heating supply, duty double effect cooling and heating supply, etc. These four energy-saving modes can be freely switched over and controlled according to the actual load and requirement on cooling and heating capacity, which can ensure the most suitable and efficient energy-saving mode in operation, and leave out the complicated and not the best subjective artificial control.

3. The units can easily and quickly generate 60 ℃ hot water, high water temperature accurate, only ± 1 ℃ deviation. With stepless energy regulation, to ensure fast and stable water temperature set at 60 ℃.

4. The units are installed with well-known brands new generation high-efficiency & high IPLV double screw compressors, 5:6 high-efficiency patent asymmetric teeth. Compressors are equipped with capacity controller to achieve muti-step or step-less energy adjustment.

5. Microcomputer control system, with strong security, communication, fault diagnosis and automatic adaptation function.

6. The main parts of refrigeration system are from famous brands at home and abroad, superior performance and reliable.

7. Set the high and low pressure protection, chilled water anti-freeze protection, power phase sequence protection, default phase protection, lack of water flow protection, compressor motor overload/overheating protection and auto-restart function on power failure, set password on control interface to prevent faulty operation.

Application
Applicable to public buildings, such as hotel, sauna center, hospital, especially building in need of cooling, heating and hot water
