Abstract

The reverse cold and hot exchange energy saving and efficiency increasing system of refrigerant circulation, belong to refrigeration, heating electric equipment field (including：The equipment such as air-conditioning, refrigerator, air energy, refrigerator).Be it is a kind of can to it is all using refrigerant as medium refrigeration, heating electric equipment carry out energy efficiency system design scheme and device.Present design is that traditional coolant circulating system is improved, and by increasing a plate type heat exchanger, makes refrigerant before condenser and evaporator is entered, carries out reverse cold and hot exchange energy, realize reuse loss-free to refrigerant self-energy.The refrigerant temperature into condenser is set further to improve, so as to add the heating capacity of work system；The refrigerant temperature into evaporator is further reduced, allow work system to obtain more refrigerating capacitys.Equipment is set to reach energy-saving purpose by this design.

Description

Refrigerant circulation --- reverse cold and hot exchange energy saving and efficiency increasing system

Technical field：The invention belongs to freeze, heat appliance field.It is all using refrigerant as circulatory mediator to be that one kind can allow Refrigeration, heating electric equipment realize the system design scheme and device of energy efficiency.It is applied to air-conditioning, refrigerator, air energy The equipment such as water heater, refrigerator, freezer.

Background technology：It is various since the cold and hot electrical equipment invention for apparatus such as air-conditioning, refrigerator, air-source water heater, refrigerator Appearance design and the update of part of appliance emerge in an endless stream.Such as：Compressor, heat exchanger, essence control valve etc. automatically controlled device with And refrigerant application etc., various new technologies are all with rapid changepl. never-ending changes and improvements, refrigeration, the efficiency of heating equipment is greatly improved.But It is that these innovations are mostly renewal and improvement on some hardware, the structure of its basic circulatory system never has big change Become and perfect.The potential of refrigerant circulation technology is preferably brought into play, make breakthroughs, visited already as the field The important topic and direction of scientific rersearch begged for.

The content of the invention：The present invention is improved on the basis of traditional coolant circulating system structure, it is therefore an objective to not In the case of increasing energy consumption, by changing refrigerant circulation mode, its own exchange energy is realized to improve the operating efficiency of equipment. I.e. by increasing a plate type heat exchanger (or similar heat-exchanger rig), refrigerant is set to be carried out before condenser and evaporator is entered inverse To cold and hot exchange energy, equivalent to the double evaporation-cooling and time condensation for realizing refrigerant.Except that current refrigerant circulation is simultaneously Exchange energy does not occur with external environment, but loss-free utilization mutual again is realized to refrigerant self-energy.So, make into The refrigerant temperature for entering condenser is further enhanced, so as to add the heating capacity of work system；Make into the cold of evaporator Matchmaker's temperature further reduces, so as to obtain more refrigerating capacitys.This method can is taken not increase the feelings of external energy consumption Under condition, the operating efficiency of equipment is improved, reaches energy-saving purpose.(see Fig. 2)

The main function and effect of the present invention：1st, the refrigerating capacity of air-conditioning, refrigerator, refrigerator can be increased；2nd, air can be increased Can water heater heating capacity, especially efficiently solve air-source water heater when increasing temperature the problem of Energy Efficiency Ratio difference.Past When increasing temperature, refrigerant from heat exchanger come out when temperature already exceed 60 degree Celsius, so during refrigerant evaporation in absorption air Energy is less, or even does not absorb the energy of air middle-low grade, is only heated by the effect of compressor itself, so that power is bright It is aobvious to reduce, influence energy-saving effect.It can be very significantly improved using this situation after the system.3rd, to cold and hot dual-purpose integrated The effect of machine is more obvious.Not the problem of can efficiently solve over that high temperature can add up, and low temperature drop is not got off.System can be made The temperature difference of cold water and water heating reaches 55 degree Celsius -- 65 degree, the production requirement of particular client can be met well.Such as：Plating The needs of enterprise's chilled water such as factory, oxygen installation, circuit board plant and preparing high-temp hot water.4th, can effectively improve equipment it is very hot, Operating efficiency under extremely cold operating mode.

Brief description of the drawings：

This specification accompanying drawing is divided into Fig. 1 and Fig. 2.In order to more intuitively and clearly express the structural representation of patent of the present invention, upper State the mark for eliminating the hardware units such as the four-way valve commonly used in conventional refrigerant, heating equipment, fluid reservoir in two figures respectively.Emphasis State the phase transition process and heat transfer process of refrigerant circulation.

Fig. 1 is common coolant refrigeration, the working cycles schematic diagram of heating equipment.Statement be：The refrigerant of gasification is evaporated through overvoltage Contracting machine a compresses, and after entering condenser b, condensation liquefaction heat release (heating), then passes through cut-off equipment c (expansion valve or capillary again Pipe) decompression, into evaporator d (refrigeration), finally enter back into the process that compressor carries out next round circulation.This process is actual Upper is exactly the process of the mutually reciprocal operation of refrigerant, i.e., while needing to compress heat release, and another side needs evaporation endothermic.Refrigerant is in Fig. 1 In cyclic process, exchange energy occurs with external environment simply by condenser and evaporator.However, in this cyclic process, Refrigerant is whether condensed or evaporated, and all without completely being discharged or being absorbed, this is just further filled the energy of its own Divide and leave space using the self-energy of refrigerant.

Fig. 2 is the refrigerant circulation schematic diagram of patent of the present invention.With Fig. 1 difference：Increase on the basis of Fig. 1 circulatory systems A plate type heat exchanger E (as shown in the figure) is added, refrigerant is made before heat absorption and heat release are undergone phase transition by heat exchanger E Refrigerant self-energy exchanges, to improve the operating efficiency of equipment.Its effect has at 2 points：

Technical scheme：To realize the above, the present invention takes embodiments below：

1st, first according to the compressor horsepower of equipment, corresponding plate type heat exchanger (or other similar to heat exchanger) is matched；

2nd, disengaging is accessed in the centre of (expansion valve or capillary) in one end of plate type heat exchanger from condenser to cut-off equipment Mouthful；The other end is from access inlet and outlet between evaporator to compressor (see Fig. 2).Note：General plate alias is mostly stainless steel, Silver brazing should be used when being welded with copper pipe.

3rd, suppressed by usual installation program, leaked hunting, fill refrigerant, debugging.
