Description
Technical field
The utility model relates to technical field of heat exchange, the energy-saving refrigeration system that particularly a kind of used heat that can be produced when working in the air-conditioning refrigeration system is used for evaporator surface defrost in self system, helps making full use of the energy and improve air-conditioning work efficient.
Background technology
Usually comprise in the refrigeration system of prior art and be provided with compressor, condenser, evaporimeter (being heat exchanger) and be arranged on fluorine Lyons circulation canal between compressor and the condenser etc., because the humiture of air conditioner surroundings is all very low, often the evaporating temperature of refrigeration machine is below the freezing point, and causes the evaporator surface frosting.Owing to the ventilation runner that can cause stopping up evaporimeter that thickens of frost layer, reduce the cooling and the dehumidification function of constant temperature and humidity device.Solution commonly used at present is to adopt the unit working method of the one after the other of dual system (two refrigeration systems) or double evaporators, to carry out the surface defrosting work of frosting evaporimeter.Because defrosting the time also needs the adapted electric heater, during handling, used heat needs with special heat radiation cooling device, so not only complex structure, energy consumption are big, and the difficulty of control defrost and heat radiation is also higher, so consider from economy and point of view of practicability, owes ideal.
Summary of the invention
The purpose of this utility model be to provide a kind of in a refrigeration system, be provided with simultaneously two groups can be by the sequential of setting, alternately carry out refrigeration and defrost heat exchanger and can be with system work process in the used heat that produced be used for the energy-saving refrigeration system of defrost.
Include compressor, heat exchanger, outdoor condenser, device for drying and filtering, reservoir and magnetic valve and expansion valve in the energy-saving refrigeration system of the present utility model, be characterised in that described heat exchanger is provided with two groups of I and II simultaneously, be arranged on simultaneously between compressor outlet and the outdoor condenser inlet end with the form of parallel connection; On the pipeline between the entrance point of the entrance point of compressor outlet and I heat exchanger and II heat exchanger, be respectively arranged with magnetic valve; On the port of export of I heat exchanger with branch form respectively and between the entrance point of compressor and and the entrance point of outdoor condenser between pipeline be provided with magnetic valve; On the port of export of II heat exchanger with branch form respectively and between the entrance point of compressor and and the entrance point of outdoor condenser between pipeline be provided with magnetic valve; On the pipeline of the port of export of outdoor condenser successively serial connection be provided with reservoir and device for drying and filtering, be provided with magnetic valve and expansion valve on the entrance point with the entrance point of I heat exchanger and II heat exchanger links to each other pipeline, connecting respectively with branch form on the port of export of device for drying and filtering.
During work, by one group of magnetic valve on fluid course of close, one group of solenoid control on another fluid course of opening/closing can alternately be worked by following two circulation canals from the high-temperature high-pressure refrigerant gas that compressor outlet flows out: the flow through entrance point of I heat exchanger → outdoor condenser → reservoir → device for drying and filtering → II heat exchanger → compressor of the first, in the course of work of this circulation canal, what the I heat exchanger was carried out is the release heat defrost, when consequently making outside defrost, the high-temperature high-pressure refrigerant gas of internal flow is tentatively lowered the temperature, this heat exchanger works to fill the post of condenser, what enter in the II heat exchanger is the low temperature liquid cold-producing medium of being supplied with by outdoor condenser, what carry out is to discharge low temperature, consequently outer surface frosting, the gasification of inner cryogenic liquid refrigerant, the preliminary intensification, this heat exchanger works to fill the post of evaporimeter; It two is the entrance points of II heat exchanger → outdoor condenser → reservoir → device for drying and filtering → I heat exchanger → compressor of flowing through, in the course of work of this circulation canal, what the II heat exchanger was carried out is the release heat defrost, the effect of filling the post of condenser, what the I heat exchanger was carried out is to discharge low temperature, the effect of filling the post of evaporimeter.
When some condensers as release heat used in two evaporimeters in being arranged on the air channel, one group control valve corresponding with it opened, and the corresponding one group of control valve when being used as evaporimeter cuts out.When the heat exchanger surface frosting of filling the post of the evaporimeter effect when the certain thickness, by the control system control valve that automaticallyes switch, change the working cycles passage, realize the work of alternately carrying out condenser and evaporimeter of two heat exchangers.
Based on the energy-saving refrigeration system of the utility model of above-mentioned design; owing in traditional refrigeration system, be provided with two groups of heat exchangers in parallel; two cold-producing medium periodic duty passages have been made up; make two groups of heat exchangers alternately carry out the work of filling the post of condenser and evaporimeter; the frost that forms on evaporator surface is in the course of the work in time melted in the self heat that the course of work produces by cold-producing medium; effectively overcome the trouble that to shut down defrost and outfit dedicated electric-thermal defroster in the prior art with white heat exchanger; both helped guaranteeing the work continuity; improve the operating efficiency of refrigeration system; brought energy-conservation positive technique effect again; and can exempt to establish special-purpose cooler; further simplify the structure, thereby have remarkable economical and very strong practicality.
