heating
|
Heating max output power
The heater has triple protection and independent temperature limiter to ensure the safety of heating system.
The power is greater than 15KW with a voltage regulator, and the heating power output control adopts 4-20ma linear control.
|
Cooling capacity
|
The power of taking away the heat at different temperature
|
Circulation flow rate and pressure
|
Lower than 75L/min, use Lneya Magnetic pump
Higher than 75L/min use Ultra wide temperature high energy efficiency centrifugal pump.
Pressure selection: 2bar 3bar 5bar 8bar（small power equipment can not customize）
The greater the pressure, the greater the power of the motor, which will increase the system load and reduce the cooling capacity of the system.

The outdoor installation of air-cooled chillers makes it easy to be affected by outdoor sunlight, and the ventilation and the environment and space has a direct impact on the cooling effect of the chiller. Today we are going to talk about the common failure and processing methods:
(1) Frequent start and stop of the compressor: there may be too much or too little refrigerant, resulting in pressure protection switch action which is resulted from too high exhaust pressure or too low suction pressure, and also poor water system circulation make sevaporator surface frost.
Method: When the refrigerant is too much, the extra can be released at the vent. If there is a shortage, check whether there are leaks of the fluorine and fill the refrigerant.
If the water circulation system is blocked or stored in the air, you should exhaust; if water circulation too small, utilize the open refrigeration water circulation system.
(2) Noisy compressor when running: check whether the expansion valve fails, the temperature package discharges the suction pipe from the compressor, which causes the liquid refrigerant return to the compressor. If it is damaged, it should be repaired, for example, if the compressor is damaged, it should be replaced.
(3) Poor refrigeration capacity: the cause of the poor refrigeration capacity may be the insufficient refrigerantand low evaporation temperature that makes the por cooling effect of pipeline; poor heat dissipation of the condenser; too large the resistant of the water circulation system,etc..
The refrigerant pipe should be checked for leakage and fill the refrigerant after repairing.You should repair the insulation layer and Clean the condenser to check whether the fan is working properly as well as clean the pipe filter.
