What are the adjustment methods for cold storage expansion valve?

The cold storage is composed of storage insulation and refrigeration equipment. The operation of the refrigeration equipment will inevitably produce some noise. If the noise is too loud, it means there may be a problem with the system, and the source of the noise needs to be identified and resolved in time.

1. A loose cold storage base may cause noise from the compressor. The corresponding solution is to detect the base. If looseness occurs, tighten it in time. This requires regular equipment inspections.

2. Excessive hydraulic pressure in the cold storage may also cause the compressor to make noise. The corresponding solution is to turn off the night supply valve of the cold storage, so as to reduce the impact of the hydraulic pressure on the compressor.

3. The compressor makes noise. The corresponding solution is to replace the worn parts after inspecting the compressor parts.

Solution:

1. If the equipment noise in the refrigeration machine room is too loud, noise reduction treatment can be done inside the machine room, and sound insulation cotton can be pasted inside the machine room;

2. The working sound of the evaporative cooling, cooling tower, and air-cooled condenser fans is too loud. The motor can be replaced with a 6-stage motor.

3. The cooling fan in the warehouse is too noisy. Replace the high-power air duct motor with a 6-stage external rotor motor.

4. The compressor is not working properly and the noise is extremely loud. Find out the cause of the system failure and solve the problem.

Precautions:

1. During the installation of cold storage, the diffusion of water vapor and the penetration of air must be prevented. When outdoor air invades, it not only increases the cooling capacity of the cold storage, but also brings moisture into the warehouse. The condensation of moisture causes the building structure, especially the insulation structure, to be damaged by moisture and freezing. Therefore, a moisture-proof insulation layer must be installed to ensure that the cold storage has good performance after installation. Sealing and moisture-proof and vapor-proof properties.

2. During the installation process of cold storage, the air cooler should be equipped with automatic defrost control equipment. The automatic control system should have a suitable and reliable frost layer sensor or differential pressure transmitter to sense the best defrost time, a reasonable defrost procedure, and a cooling fan fin temperature sensor to prevent excessive heating.

3. The location of the cold storage unit should be as close as possible to the evaporator, and it should be easy to maintain and have good heat dissipation. If it is moved outside, a rain shelter must be installed. Anti-vibration gaskets must be placed at the four corners of the cold storage unit. The installation must be level and firm to prevent people from touching it.
