Description
The utility model air-conditioned coach relates to technical field of refrigeration equipment with deep freezer, is applicable to be installed in the various air-conditioned coaches.
Now the refrigeration system of air-conditioned coach is generally by compressor, condenser, liquid receiver, expansion valve, A/C evaporator is formed, and its weak point is to carry out air-conditioning to the temperature in the railway carriage, admires in air-conditioned coach with the problem of chilled food and beverage but can not satisfy the passenger.
The purpose of this utility model provides a kind of air-conditioned coach deep freezer, this deep freezer is to tell a small part refrigerant to enter the fridge equipment that the deep freezer pipeline system constitutes in the cooling cycle system of existing air-conditioner vehicle, this deep freezer is installed in air-conditioned coach, can realize the purpose of the quick-frozen and the refrigeration of Food ﹠ Drink flexibly according to passenger's needs.
The utility model air-conditioned coach is by the compressor in the cooling cycle system of prior art air-conditioned coach (1) with the design (Fig. 1～2) of deep freezer, condenser (2), liquid receiver (3), expansion valve (5), A/C evaporator (6) and by air-conditioned coach with the electromagnetic valve (4) of deep freezer, air-conditioned coach amplification controller (7), expansion valve (8), temperature controller (9), refrigerating container evaporator (10), electronic fan (11) is formed, this deep freezer is to tell a small part circulating refrigerant to enter deep freezer pipeline system formation fridge equipment in the cooling cycle system of existing air-conditioner vehicle, its structure connects: existing air-conditioned coach compressor (1) connects condenser (2), condenser (2) connects the inlet side of liquid receiver (3), the inlet side that goes out end connection A/C evaporator (6) of expansion valve (5), the return-air mouth that goes out end connection air-conditioned coach compressor (1) of A/C evaporator (6) constitutes.Inventive point of the present utility model is the deep freezer part, its structure connection is that the end that of liquid receiver (3) connects the inlet side of expansion valve (8) and the inlet side of electromagnetic valve (4) respectively, the inlet side that goes out end connection expansion valve (5) of electromagnetic valve (4), the inlet side that goes out end connection refrigerating container evaporator (10) of expansion valve (8), the B that goes out to hold of refrigerating container evaporator connects the return-air mouth of air-conditioned coach compressor (1), the bulb of temperature controller (9) attaches the outside face of refrigerating container evaporator (10), control power lead C connects on the terminals of the air-conditioning amplification controller (7) through having improved, on the terminals of the magnetic clutch of this amplification controller (7) other end connection electromagnetic valve (4) and air-conditioned coach compressor (1), electronic fan (11) is fastenedly connected at refrigerating container evaporator (10) and goes up formation.
The utility model air-conditioned coach with the working process of deep freezer is: 1, when chilled beverage or food; By the high-temperature high-pressure refrigerant steam after air-conditioned coach compressor (1) compression, be condensed into highly pressurised liquid through condenser (2) and be divided into the two-way circulation by liquid receiver (3): promptly one tunnel electromagnetic valve (4) for unlatching, enter by expansion valve (5) and to get back to air-conditioned coach compressor (1) behind A/C evaporator (6) sweat cooling and finish the air-conditioner vehicle refrigerating cycle.Another route liquid receiver (3) is told a small part high-pressure refrigerant and is entered refrigerating container evaporator (10) through expansion valve (8), behind rapid sweat cooling under the effect of electronic fan (11), get back to air-conditioned coach compressor (1) and finish the deep freezer refrigerating cycle, when reaching design temperature in the deep freezer, temperature controller (9) contact open, cut off the power supply of electronic fan (11), deep freezer enters keeping warm mode; When temperature recovery in the deep freezer during to design temperature, temperature controller (9) makes electronic fan (11) work, and refrigeration the temperature inside the box is descended, and finishes a circulation.2, when not turning on the aircondition the quick-frozen drink and food: the high temperature and high pressure steam after the air-conditioned coach sky contracts machine (1) compression is cooled to highly pressurised liquid through condenser (2), only enter expansion valve (8) (electromagnetic valve this moment (4) is closed condition) and refrigerating container evaporator (10) by liquid receiver (3), under the effect of electronic fan (11), sharply get back to air-conditioned coach compressor (1) behind the sweat cooling and finish the deep freezer refrigerating cycle.When refrigeration the temperature inside the box reaches design temperature as-18 ℃, temperature controller (9) sends signal cuts off air-conditioned coach compressor (1) through air-conditioned coach amplification controller (7) control magnetic clutch, air-conditioned coach compressor (1) is quit work, when temperature recovery arrives a certain design temperature as-12 ℃, temperature controller (9) restarts air-conditioned coach compressor (1) work, reaches the purpose of refrigerating cycle.
The utility model air-conditioned coach is compared with prior art with the effect of deep freezer: because the utility model is to tell a small part refrigerant to enter deep freezer pipeline system formation deep freezer device in the liquid receiver of existing air-conditioner vehicle, have make full use of air-conditioner vehicle refrigerating cycle under the switching of electromagnetic valve, the passenger who further satisfies air-conditioner vehicle realizes the operating mode of the quick-frozen and the refrigeration of Food ﹠ Drink, thereby reach the function that has increased a chilled food and beverage to air-conditioner vehicle, it is air-conditioned coach deep freezer a kind of simple in structure, easy to use.
