Embodiment Construction

[0014] The present invention will be described in further detail below in conjunction with accompanying drawing

[0015] The refrigerant gas enters the oil separator 2 after being compressed by the high-pressure ratio compressor 1, and after separating the lubricating oil, it enters the multi-stage horizontal plate-exchange condenser 3, exchanges heat with the water in the plate-exchange condenser, and heats the water When the temperature reaches 95°C, the temperature of the refrigerant is greatly reduced, and the gas is condensed into a liquid, which enters the liquid receiver 4, and then flows through the dry filter 5, and then enters the sub-cooler 6 to further cool down after drying the water, preparing for low-temperature evaporation , and then enter the multi-stage horizontal plate exchange evaporator 8 to evaporate through the expansion valve 7 and reduce the pressure, fully absorb the heat of the water in the evaporator, reduce the water temperature to 3°C, and finally ...

Abstract

The invention discloses a double-effect water chiller. The double-effect water chiller consists of a high-pressure-ratio compressor, an oil separator, an oil cooler, a multi-section horizontal plate type heat exchanger condenser, a reservoir, a drying filter, a subcooler, an expansion valve, a multi-section horizontal plate type heat exchanger evaporator, a vapor-liquid separator, an electric control system, an electromagnetic valve, a stop valve, a flow switch, a sensor and other related accessories, wherein the components are connected into a whole through a pipeline or a line. Through adoption of the double-effect water chiller, low-temperature refrigeration and high-temperature heating can be realized at the same time, so that a boiler is replaced; the double-effect water chiller is energy-saving and environment-friendly; and moreover, process production line equipment is simplified, and the initial investment cost is saved.

Description

technical field [0001] The invention relates to the field of refrigeration and heating, in particular to the field of a double-effect chiller. Background technique [0002] In some industrial production processes, both low-temperature cold water at 3°C ​​and high-temperature hot water at 95°C are required. At present, the commonly used solution is: use a low-temperature refrigerator to obtain low-temperature cold water at 3°C, and use a boiler to produce hot water at 95°C. hot water. In this way, a set of equipment is required for cooling, and a set of equipment for heating, and a set of cooling water cooling system is required for the cooling equipment, and a set of softened water treatment equipment is required for the heating boiler, so there are many equipments and a lot of energy waste. And the two sets of equipment are not easy to realize fully automatic control, let alone the industrial Internet of things control after access. Contents of the invention [0003] In...
