Abstract
In bolt multigang refrigerating units on current technology, the employment of a siphon thermodynamic medium cooling method provides a plurality of on-site connecting pipes and valves and increases an on-site quantity of work. An assemble height of a siphon bank provides an enough height to an apparatus room an increases investment. The utility model employing technology of the heat transfer liquid reserve tank overcomes disadvantage of that siphon thermodynamic medium cooling method is provided with a plurality of on-site connecting pipes and valves, a great on-site quantity of work, an enough height for the apparatus room, a more investment to achieve purpose on a less quantity of apparatus, a less on-site quantity of work and a less investment.
Description
Technical field
The utility model relates to the multi-joint refrigeration unit of a kind of screw rod, especially relates to a kind of multi-joint refrigeration unit of screw rod of not having Siphon pot.
Background technology
In the multi-joint refrigeration unit of the screw rod of prior art, the type of cooling has oil cooling, water-cooled, air-cooled etc. several; In the multi-joint refrigeration unit of screw rod of the foreign technology of up-to-date introduction, the best a kind of mode of oil cooling is a hydrocone type hot working fluid cooling method.This unit is made up of oil eliminator (1), condenser (2), Siphon pot (3), oil cooler (4), liquid reservoir (5) etc. as shown in Figure 1, connects and composes the compression refrigeration closed circuit successively by pipeline.It compares water-cooled and air-cooled floor space is little, heat exchange efficiency is high, do not have dirt generates, can be with the growth of service time decrease in efficiency.But the shortcoming of the multi-joint refrigeration unit of this screw rod also is clearly: owing to adopt hydrocone type hot working fluid cooling method, 1. on-the-spot pipeline and the valve that connects is more, and the workload of site operation is bigger; 2. Siphon pot has the requirement of setting height(from bottom), so the necessary enough height of machine room, invests bigger.
The utility model content
For solving above-mentioned shortcoming, the utility model will provide the multi-joint refrigeration unit of screw rod of the no Siphon pot that a kind of number of devices is few, the workload of site operation is little, investment is little.
For achieving the above object, the technical solution adopted in the utility model is: the multi-joint refrigeration unit of the screw rod of no Siphon pot connects into the loop by pipeline successively by oil eliminator, condenser and heat exchange liquid reservoir and forms.Key technology of the present utility model is to have adopted the heat exchange liquid reservoir, and the high-temperature high-pressure refrigerant that comes out from condenser carries out heat exchange the heat exchange liquid reservoir, has improved the again cold degree of cold-producing medium before throttling, thereby has improved coefficient of refrigerating performance.
The beneficial effects of the utility model are: owing to adopted heat exchange liquid reservoir technology, adopt on-the-spot pipeline and the valve that connects of hydrocone type hot working fluid cooling method more thereby overcome, the workload of site operation is bigger, the necessary enough height of machine room, invest bigger shortcoming, realized that the utility model provides the purpose of the multi-joint refrigeration unit of screw rod that a kind of number of devices is few, the workload of site operation is little, investment is little.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Description of drawings
Accompanying drawing 1 is the prior art constructions schematic diagram.
Accompanying drawing 2 is structural representations of the present utility model.
Among the figure: 1--oil eliminator, 2--condenser, 3--heat exchange liquid reservoir.
The specific embodiment
With reference to accompanying drawing 2, the multi-joint refrigeration unit of the screw rod of no Siphon pot connects into the loop by pipeline successively by oil eliminator (1), condenser (2) and heat exchange liquid reservoir (3) to be formed, and the high-temperature high-pressure refrigerant that comes out from condenser (2) carries out heat exchange heat exchange liquid reservoir (3).
Claims (2)
1. do not have the multi-joint refrigeration unit of screw rod of Siphon pot, comprise the oil eliminator condenser, it is characterized in that: it also comprises the heat exchange liquid reservoir, and this oil eliminator condenser heat exchange liquid reservoir connects into the loop by pipeline successively.
2. the multi-joint refrigeration unit of the screw rod of no Siphon pot according to claim 1, it is characterized in that: the high-temperature high-pressure refrigerant that comes out from condenser carries out heat exchange the heat exchange liquid reservoir.
