Abstract
Description
Technical Field
[0001] This utility model relates to the field of refrigeration technology, specifically to a siphon tank suitable for refrigeration equipment. Background Technology
[0002] In a refrigeration system, the primary function of the siphon tank is to condense the high-temperature, high-pressure vapor discharged from the compressor into liquid via an evaporative condenser. The liquid first enters the siphon tank, and when the liquid level reaches the overflow port, it flows into the storage tank to supply liquid to the evaporator. During this cycle, gas and liquid phases coexist. The gas phase is difficult to control; when its proportion is too high, it can cause internal pressure overload, adversely affecting the equipment's lifespan and significantly increasing the risk of leakage. Utility Model Content
[0003] The purpose of this utility model is to provide a siphon tank suitable for refrigeration equipment. The specific technical solution is as follows:
[0004] A siphon tank suitable for refrigeration equipment includes a tank body with: a refrigerant inlet pipe and a refrigerant outlet pipe, the refrigerant inlet pipe being horizontally higher than the refrigerant outlet pipe; the refrigerant inlet pipe being connected to the condensate outlet pipe of an evaporative condenser; and the refrigerant being discharged from the tank when the liquid level in the tank is higher than the refrigerant outlet pipe; a heat exchange outlet pipe and a heat exchange inlet pipe, the heat exchange outlet pipe being located at the bottom of the tank body; the heat exchange inlet pipe being horizontally higher than the refrigerant outlet pipe; and a heat exchange shut-off valve being installed on the heat exchange outlet pipe. Used to control whether to start heat exchange; a gas phase balance pipe, which is set at the top of the tank, is connected to the high-temperature return gas pipeline of the evaporative condenser through the first gas phase shut-off valve, and is used to orderly introduce the high-pressure gas under pressure overload into the tank through the control of the first gas phase shut-off valve; a coil is installed in the tank, and the outer ring inlet of the coil is connected to the refrigerant inlet pipe. The horizontal height of the coil is the same as the horizontal height of the refrigerant inlet pipe, so that the condensate discharged from the evaporative condenser flows through the coil and then is discharged into the tank through the inner ring outlet of the coil.
[0005] Fins are provided on the outer periphery of the coil to improve the heat exchange efficiency between the condensate in the coil and the gas phase in the tank.
[0006] A gas phase balance branch pipe is installed on the gas phase balance pipe. The gas phase balance branch pipe is connected to the top of the liquid storage tank through a second gas phase shut-off valve. This allows the vapor phase evaporated in the liquid storage tank pipe to be orderly introduced into the tank body under the control of the second gas phase shut-off valve.
[0007] The horizontal height of the heat exchanger inlet pipe is lower than the horizontal height of the coil.
[0008] The above-mentioned technical solution of this utility model has the following beneficial technical effects: By setting up the coil, the condensate discharged from the evaporative condenser flows through the coil before entering the tank. When the internal pressure of the equipment is overloaded, the first gas phase shut-off valve is opened, and the excessively pressurized gas phase enters the tank from the gas phase balance pipe and contacts the coil, thereby accelerating condensation and effectively reducing the pressure overload caused by an excessively high gas phase ratio. After the pressure stabilizes, the first gas phase shut-off valve is closed. This effectively ensures that no pressure overload occurs inside the equipment. Attached Figure Description

Detailed Implementation
[0011] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.
[0012] A siphon tank suitable for refrigeration equipment includes a tank body 1, on which are provided: a refrigerant inlet pipe 2 and a refrigerant outlet pipe 3, the horizontal height of the refrigerant inlet pipe 2 being higher than that of the refrigerant outlet pipe 3, the refrigerant inlet pipe 2 being connected to the condensate outlet pipe of an evaporative condenser, and the refrigerant being discharged from the tank body 1 when the liquid level in the tank body 1 is higher than that in the refrigerant outlet pipe 3; a heat exchange outlet pipe 4 and a heat exchange inlet pipe 5, the heat exchange outlet pipe 4 being located at the bottom of the tank body 1, the horizontal height of the heat exchange inlet pipe 5 being higher than that in the refrigerant outlet pipe 3, and a heat exchange shut-off device on the heat exchange outlet pipe 4. Valve 6 controls whether heat exchange is started. A gas phase balance pipe 7, located at the top of tank 1, connects to the high-temperature return gas line of the evaporative condenser via a first gas phase shut-off valve 8. This pipe allows high-pressure gas under pressure overload to be introduced into tank 1 in an orderly manner under the control of the first gas phase shut-off valve 8. A coil is installed inside tank 1, with its outer ring inlet connected to the refrigerant inlet pipe 2. The coil's horizontal level matches that of the refrigerant inlet pipe 2, ensuring that the condensate discharged from the evaporative condenser flows through the coil before being discharged into tank 1 through the inner ring outlet. The coil design ensures that the condensate discharged from the evaporative condenser flows through it before entering tank 1. When the internal pressure of the equipment is overloaded, the first gas phase shut-off valve 8 is opened, allowing the excessively pressurized gas phase to enter tank 1 from the gas phase balance pipe 7 and contact the coil, thus accelerating condensation and effectively reducing the pressure overload caused by an excessively high gas phase ratio. The first gas phase shut-off valve 8 is then closed after the pressure stabilizes. This effectively ensures that there will be no pressure overload inside the equipment.
[0013] Fins are installed on the outer periphery of the coil to improve the heat exchange efficiency between the condensate in the coil and the gas phase in the tank 1. A gas phase balance branch pipe 9 is installed on the gas phase balance pipe 7, which is connected to the top of the storage tank through a second gas phase shut-off valve 10, so as to orderly introduce the vapor phase evaporated in the storage tank into the tank 1 under the control of the second gas phase shut-off valve 10. The horizontal height of the heat exchange inlet pipe 5 is lower than that of the coil.
