Abstract

The utility model relates to a plate-shell type condensation and evaporation circulating barrel applied to a refrigerating or cascade refrigerating system. The problems that in the background technology, when a condensation evaporator and a low-pressure circulation barrel are two independent devices, the devices are too high, the manufacturing cost, the transportation cost, the installation cost and the like of the devices can be increased, the cavitation phenomenon of a refrigeration pump can be caused when the height is reduced, and even faults of the refrigeration pump can be caused when the height is serious are solved. According to the technical scheme, the plate-shell type condensation and evaporation circulating barrel is characterized in that a liquid inlet, a left sealing head, a barrel body, a plate core, an air inlet, a right sealing head, an air outlet and a liquid outlet are formed in the plate-shell type condensation and evaporation circulating barrel; a liquid storage space is arranged at the bottom of the barrel. The utility model is suitable for refrigeration systems.

Description

Technical Field

[0001] The utility model belongs to refrigeration technology, in particular to a plate-shell type condensation evaporation circulation barrel used in a cold-carrying or cascade refrigeration system. Background Art

[0002] In the existing carbon dioxide refrigeration units, the condenser evaporator and low-pressure circulation barrel used are two separate devices. Due to the need for gravity drop, the condenser evaporator must be placed above the low-pressure circulation barrel, so the equipment will be very high. Due to the height limit during transportation, the equipment must be separated into upper and lower parts, which will increase the cost of equipment manufacturing, transportation, and installation. The height of some project machine rooms is relatively low. In order to make the equipment installable, the height between the refrigeration pump and the low-pressure circulation barrel can only be reduced, which will greatly reduce the safety cavitation margin of the refrigeration pump. The refrigeration pump is prone to cavitation, and in severe cases, it may even cause refrigeration pump failure. Utility Model Content

[0003] The purpose of the present utility model is to propose a plate-and-shell condenser-evaporator circulating barrel for use in a cold-carrying or cascade refrigeration system, in order to solve the problem in the background technology that when the condenser evaporator and the low-pressure circulating barrel are two separate devices, the equipment is too high, which increases the cost of equipment manufacturing, transportation, and installation. Lowering the height will cause cavitation in the refrigeration pump, and in severe cases, even cause refrigeration pump failure. The technical solution adopted to solve this technical problem is: a plate-and-shell condenser-evaporator circulating barrel for use in a cold-carrying or cascade refrigeration system, characterized in that: the plate-and-shell condenser-evaporator circulating barrel is provided with an air outlet, a left end cap, a cylinder, a plate core, an air inlet, a right end cap, a liquid inlet, and a liquid outlet; and a liquid storage space is provided at the bottom of the cylinder. The air outlet and the liquid inlet are either on one side of the cylinder or on both sides of the cylinder. The plate core is either installed in the gas phase area or partially installed in the liquid phase area. The air inlet is either on the top of the cylinder or on the side of the cylinder.
