What if the heater chiller fails to start?

What if the heater chiller fails to start?

1. The reason for the failure to start is that the pressure at the cooler inlet of the SUNDI-320/420W/430W Cooling and Heating Systems is low during the operation of the system, which can not meet the basic conditions for operation, and the failure to start will occur.

2. According to the configuration instructions of the water-oil dual-purpose constant heating cooler, it can be understood that it is basically caused by the idling of the water pump and other reasons.

As long as the air in each system of the water-oil dual-purpose constant heating cooler is released, it can meet the suitable operating environment and achieve the purpose of starting.

3. Pressure. After the small water-oil heater cooler has difficulty in starting to different degrees, it needs to complete corresponding maintenance according to the actual needs.

4. To ensure the smooth operation of the water-oil dual-purpose constant heating cooling machine, it is necessary to effectively control the air inlet and outlet of the water pump during the use of the water-oil dual-purpose constant heating cooling machine. As the air is continuously removed, the failure that cannot be started can be solved.

Refrigeration cycle includes compression refrigeration cycle, absorption refrigeration cycle, adsorption refrigeration cycle, steam jet refrigeration cycle and semiconductor refrigeration.

The cooling water circulator mainly adopts the compressor refrigeration cycle. In the compressed air refrigeration cycle, two constant pressure processes are used to replace the two constant temperature processes of the reverse Carnot cycle, so it can be regarded as the reverse Brayton cycle.

In engineering applications, compressors can be piston type or impeller type. The air from the heating and cooling cycle equipment enters the compressor and is adiabatic compressed, and the temperature rises to above the ambient temperature;

Then it enters the cooler and transfers heat to the cooling water at constant pressure, with the temperature equal to the ambient temperature;

Then the expander is introduced for adiabatic expansion, and the temperature is further reduced below the temperature of the heating and cooling cycle equipment; Then enter the heating and refrigeration cycle equipment, absorb heat at constant pressure (the heat absorbed is called the cooling capacity), and complete the cycle.

During operation, if it is found that the cooling water circulator cannot be started, attention should be paid to it. It is recommended to observe carefully and solve it in time.

If the pump cannot be started, open the inlet and outlet gate of the switching well and close other gates according to the arrangement instructions.

Before the pump is started, inject clean water into the receiver on the stuffing box and smooth rubber bearing. After the pump is out of water, it is better to turn it down.

It is better to check the oil level of the pump bearing position to ensure the smoothness of the water and oil circuits around.

Before the start of the pump, check whether the joint parts are loose, roll the coupling manually to see if it is flexible and whether there is noise in the pump.
