Description

Novel box-type water chiller

Technical Field

The utility model relates to the technical field of refrigeration, in particular to a novel box-type water chiller.

Background

The water chiller is a cooling water device capable of refrigerating, controlling temperature and constant flow, and is widely applied to various industrial and commercial fields. It is a device that absorbs heat by circulating a refrigerant and discharges it. The principle of operation of the water chiller is based on a refrigeration cycle, which is a process of absorbing heat by circulating a refrigerant and discharging it. Refrigeration cycles are generally composed of four main components: a compressor, a condenser, an expansion valve, and an evaporator. Refrigerant circulates between these components to achieve a cooling effect. First, the refrigerant is compressed into a high-pressure gas by a compressor, and then cooled by a condenser and becomes a high-pressure liquid. Next, the high pressure liquid enters the evaporator through the expansion valve, becomes a low pressure liquid and absorbs heat. The low pressure liquid is then compressed again into a high pressure gas by the compressor, completing the refrigeration cycle.

When the water chiller starts to work, as the refrigerant steam enters the H-shaped expansion valve from the evaporator, pressure difference is formed at two sides of the diaphragm, and under the action of the pressure difference, the diaphragm pushes the ejector rod to move downwards suddenly to open the valve. Then, through heat transfer, the temperature of working medium in the power head is balanced with the temperature of the steam of the refrigerator at the outlet of the evaporator, so that the valve core quickly returns to a normal opening state. In this period, the ejector rod and the valve core can be separated, and the valve core moving part forms a free vibration system which is easy to be disturbed by external excitation. When the frequency of external excitation is close to the natural frequency of a valve core moving part, vibration is caused, so that a valve is frequently opened, howling is generated or parts are damaged, and therefore the problem of how to solve the problem of howling generated by internal vibration of a water chiller or parts damage is urgent to be solved.
