For solving the problem, the utility model adopts following technical scheme:
A kind of screw type low-temperature salt solution unit, comprise compressor, oil eliminator, oil cooler, condenser, economizer, expansion valve, economizer expansion valve and gas-liquid separator, described compressor has oil-out, oil-in and second vapor injection mouth, described oil cooler is connected between described oil-out and described oil-in, described compressor connects described oil eliminator, described oil eliminator connects described condenser, the first pipeline and the second pipeline is connected with between described condenser and described economizer, described economizer expansion valve is connected on described first pipeline, described economizer connects described second vapor injection mouth, described economizer connects described gas-liquid separator, described expansion valve is connected between described economizer and described gas-liquid separator, described gas-liquid separator connects described compressor, described gas-liquid separator is parallel with an evaporimeter.
Preferably, described oil cooler is water-cooled oil cooling machine.
Preferably, described condenser is water cooled condenser.
Preferably, described evaporimeter is plate-type evaporator.
The beneficial effects of the utility model are:
This device have employed economizer, and the refrigerant liquid entering gas-liquid separator, when by economizer, by the refrigerant cools after another road throttling, produces larger degree of supercooling, improves the refrigerating capacity of unit.
This device have employed oil cooler, and in compressor oil pocket, high temperature grease is after oil cooler cooling, then enters compressor lubricant oil runner, can effectively control compressor lubrication oil temperature, guarantee that compressor normally lubricates.
This device have employed plate-type evaporator and gas-liquid separator, is beneficial to thermosiphon principle, when not increasing extra power consumption, can significantly reduce evaporimeter volume, reduces salt water resistance simultaneously, reduces brine pump power consumption.
