Abstract
The utility model discloses a heat pump type refrigeration and heating air-conditioning system for an electric motor car. The air-conditioning system comprises a compressor, an out-vehicle heat exchanger assembly, expansion valves, and an in-vehicle heater, an in-vehicle heat exchanger, an electric heater, and a blower which are arranged in an air flue, wherein four-way valves for switching between the system refrigeration and heating are arranged between the compressor, and the out-vehicle heat exchanger assembly, the in-vehicle heater, and the in-vehicle heat exchanger. The utility model has the benefits that first, the heat recovery mode is adopted, so that the heating quantity is large and the energy efficiency ratio is high compared with traditional fuel oil heating and electrical heating, thus the air-conditioning system is very suitable for novel environment-friendly electric vehicles, hybrid vehicles, and fuel cell vehicles, demanding much on energy conservation of the air conditioning; and second, the system has the characteristics of low cost, simple pipeline and convenience in control because the two four-way valves are adopted to replace the multiple electromagnetic valves connected in parallel in the conventional air-conditioning for electric motor cars.
Description
Technical field:
The utility model relates to the air-conditioning system technical field, especially relates to a kind of electric vehicle heat-pump-type waring and cooling air conditioning system.
Background technology:
The eco-friendly car of a new generation is like electronic, hybrid power, fuel cell and other low emission vehicle, because power own is much smaller than the traditional power car, so it is very limited to offer the power of air-conditioning system.
The normal systemic circulation schematic diagram that adopts of electric motor car air conditioner industry is seen shown in Figure 1 at present: this circulatory system mainly includes compressor 01, magnetic valve 021; 022; 023; 024, car external heat exchanger assembly 03, expansion valve 041,042 and the car internal heater 06, car heat exchanger 07, electric heater 08, the blower fan 09 that are positioned at air channel 05; When system freezes; Refrigerant from compressor 01 outflow; According to the flow direction shown in the arrow A,, get back to compressor 01 after the refrigerant heat absorption evaporation via heat exchanger 06 in the car in magnetic valve 021, car external heat exchanger assembly 03, magnetic valve 022, the expansion valve 041 entering air channel 05.When system heated, the refrigerant from compressor 01 flows out according to the flow direction shown in the arrow B, got into car external heat exchanger assembly 03 via car internal heater 06, expansion valve 042, magnetic valve 024, gets back to compressor 01 through magnetic valve 023 after the refrigerant heat absorption evaporation.The weak point of this air-conditioning system is its pipe-line system complex structure, need to adopt a plurality of magnetic valves, causes that cost is high, reliability is low.
The utility model content:
The purpose of the utility model exploitation is the weak point that exists to prior art and a kind of new electric vehicle heat-pump-type waring and cooling air conditioning system is provided, and that this air-conditioning system has is with low cost, efficient energy-saving, changes in temperature one, dependable performance, use characteristics easy to maintenance.
For realizing above-mentioned purpose; Car internal heater, car heat exchanger, electric heater, blower fan that the electric vehicle heat-pump-type waring and cooling air conditioning system of the utility model includes compressor, car external heat exchanger assembly, expansion valve and is positioned at the air channel; Wherein, be provided with the cross valve that is used to carry out system's refrigeration and heats switching usefulness in compressor and car external heat exchanger assembly, car internal heater and the car between the heat exchanger.
Preferred as technique scheme, described cross valve is a cascaded structure.
Preferred as technique scheme, described compressor is a motor compressor.
The beneficial effect of the utility model is: it heats the recuperation of heat form that adopts (1); Heat to compare with traditional fuel Heating and electrical heating and have the advantage that heating capacity is big, Energy Efficiency Ratio is high, be fit to very much the use for the demanding novel environment friendly electric automobile of air conditioner energy saving such as electronic, hybrid power, fuel cell; (2) it adopts two cross valves to replace a plurality of parallelly connected magnetic valve of conventional electric car air-conditioners, have with low cost, the response time fast, the control characteristic of simple.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is done further explanation:
Structural representation for existing electric vehicle heat-pump-type waring and cooling air conditioning system shown in Figure 1;
Shown in Figure 2 is the structural representation of the utility model.
The specific embodiment:
See shown in Figure 2: the cold slow air-conditioning system of the electric vehicle heat-pump-type of the utility model includes compressor (motor compressor) 10, car external heat exchanger assembly 30, expansion valve 41; 42 and the car internal heater 60, car heat exchanger 70, electric heater 80, the blower fan 90 that are positioned at air channel 50; In addition; In compressor 10 and car external heat exchanger assembly 30, car internal heater 60 and car, be provided with between the heat exchanger 70 and be used to carry out system's refrigeration and heat the cross valve 21 that switches usefulness; 22, cross valve 21 and 22 is a cascaded structure.
The kind of refrigeration cycle process of the utility model is following: after cold-producing medium flows out from compressor 10; Via heat exchanger 70 in the car in cross valve 21, cross valve 22, car external heat exchanger assembly 30, the expansion valve 41 arrival air channels 50, get back to compressor 10 via cross valve 22 at last.It is following to heat cyclic process: cold-producing medium arrives car external heat exchanger assembly 30 via cross valve 21, car internal heater 60, expansion valve 42 after flowing out from compressor 10, gets back to compressor 10 via cross valve 22 at last.
The above is merely the preferred embodiment of the utility model, does not therefore limit the protection domain of the utility model, and every equalization of doing according to the utility model changes with modifying and all belongs in the claim that the utility model contains.
