Abstract
The utility model discloses a jet refrigerating unit adopting an evaporative condenser, belonging to the technical fields of new energy and energy saving. In the jet refrigerating unit, the evaporative condenser is adopted to replace the traditional condenser and cooling water tower, so that the condensing pressure of refrigerants of the unit can be adjusted automatically with the change of a work condition; and a system of the jet refrigerating unit is higher in heat exchange efficiency and is simple, the consumption of cooling water is low, and the popularization applicability of the entire unit is increased. The jet refrigerating unit is simple in structure, convenient to use and maintain, and high in efficiency and the system runs in a positive pressure manner, and the popularization applicability of the jet refrigerating unit is greatly increased.
Description
Technical field
The utility model relates to a kind of ejector refrigeration unit that adopts evaporative condenser, is to the recovery of the waste heat that produces in the industrial processes and the device of utilization, belongs to new forms of energy and field of energy-saving technology.
Background technology
At present, spray type refrigerating is a kind of machine that can utilize low-grade heat source to freeze, and uses more extensive in solar refrigeration and waste heat recovery refrigerating field.The structure of traditional injecting type system is that outlet links to each other respectively at generator exports, evaporator outlet and condenser inlet with compressed steam for the working steam import of injector, jetting steam caused import; Condensator outlet is divided into two-way; The choke valve of leading up to links to each other with evaporator outlet, and another road links to each other with the generator import through liquid pump.Each connects by refrigerant tubing and is communicated with realization.Traditional spray type refrigerating system adopts water-cooling pattern to realize cold-producing medium condensation in condenser, and this system must the extra cooling water system of setting up, so the systematic comparison complicacy, and water consumption is bigger, and influence is promoted the use of.
Summary of the invention
The purpose of the utility model provides a kind of ejector refrigeration unit that adopts evaporative condenser, and this unit provides the ejector type refrigerating machine that a kind of system architecture is simple, easy to use, can effectively reduce cooling water inflow, the condensation in condenser of the employing vaporation-type type of cooling (being air-cooled water-cooled combined type) realization cold-producing medium.
The technical scheme of the utility model is: a kind of spray type refrigerating unit that adopts evaporative condenser; It mainly comprises a reservoir, expansion valve, evaporimeter, liquid pump, generator; Also comprise an injector and condenser; The outlet of reservoir connects expansion valve and liquid pump respectively through control valve, and the outlet of liquid pump is connected to the import of injector through generator, and the outlet of expansion valve is connected to the ejecting port of injector through evaporimeter; The outlet of injector is connected to reservoir through condenser, and the PLC centralized Control is adopted in electrical control.Said condenser adopts evaporative condenser, and said generator and evaporimeter adopt shell-and-tube heat exchanger, or adopts the thistle board fin heat exchanger; The working media of said refrigeration unit adopts environmental protection refrigerant.
Said environmental protection refrigerant is selected from R134a cold-producing medium, R141b cold-producing medium or R236fa cold-producing medium.
The beneficial effect of the utility model is: this spray type refrigerating unit adopts evaporative condenser to substitute the scheme that adopts condenser and cooling tower; Form the cooling of water-cooled and air-cooled combined type; And its water-cooled form is self water circulation; Therefore effectively reduced the consumption of cooling water, whole system is simple, and is easy to use.In sum, the utility model is the ejector type refrigerating machine that a kind of system architecture is simple, easy to use, adopt evaporative condenser realization cold-producing medium high-efficiency condensation in condenser.
