Description
Technical field
The utility model relates to air-conditioner set, especially a kind of multi-variable air conditioning unit of electric auxiliary heating.
Background technology
Existing multi-variable air conditioning unit, heats in work in the winter time, and because outdoor environment temperature is low, heating capacity decay is very large, often can not meet the requirement of air conditioner heat load, and indoor air temperature in air conditioned building reduces, degree of comfort decreased.Now, air cool heat pump air conditioning system can increase the pressure of refrigerant system condenser, reduces the pressure of evaporimeter, needs cold-producing medium than many during refrigeration when whole refrigeration system is heated.When working conditions change, have and do not have the liquid refrigerant evaporated get back to compressor and compressed, due to the incompressible characteristic of liquid, will " liquid hammer " fault of compressor be caused.In order to prevent " liquid hammer ", present air cool heat pump air conditioning system, at the gas-liquid separator that compressor air suction mouth installation volume is larger, this improper increase cost, and take up space, in addition, the temperature-compensating heating generally used now is placed on directly heating in air conditioning chamber, heater works near indoor heat exchanger, also affects the heat exchange of indoor heat exchanger.
Summary of the invention
The purpose of this utility model is to overcome defect of the prior art, adopts a kind of multi-variable air conditioning unit of electric auxiliary heating, before the muffler of compressor, establishes heating cabinet, return-air is heated, improves heating capacity, prevent liquid refrigerant to be inhaled into compressor and cause liquid hammer, install simple, be easy to operation.
For achieving the above object, the technical solution of the utility model is the multi-variable air conditioning unit adopting a kind of electric auxiliary heating, comprise the first indoor heat exchanger, the second indoor heat exchanger, the 3rd indoor heat exchanger, four-way change-over valve, outdoor heat exchanger, compressor, the first electric expansion valve, the second electric expansion valve, the 3rd electric expansion valve, heating cabinet, electric heater, described compressor, four-way change-over valve, heating cabinet successively closed loop connect, and described four-way change-over valve, outdoor heat exchanger, the first electric expansion valve, the first indoor heat exchanger successively closed loop connect.
The first described electric expansion valve, the second electric expansion valve, the 3rd electric expansion valve be connected in series the first indoor heat exchanger, the second indoor heat exchanger, the 3rd indoor heat exchanger respectively after be connected in parallel.
Described electric heater is arranged in heating cabinet, and described electric heater is connected with the control circuit of unit by wire.
The beneficial effects of the utility model are:
(1) temperature-compensating, improves heating capacity, prevents liquid hammer.
(2) reduce the size of gas-liquid separator, save the material manufactured, save space.
(3) install simply, be easy to production operation.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
In figure: the first indoor heat exchanger 1, second indoor heat exchanger 2, the 3rd indoor heat exchanger 3, four-way change-over valve 4, outdoor heat exchanger 5, compressor 6, first electric expansion valve 7, second electric expansion valve 8, the 3rd electric expansion valve 9, heating cabinet 10, electric heater 11.
Detailed description of the invention
Composition graphs 1 pair of the utility model detailed description of the invention is further described:
According to the technical scheme that the utility model provides, a kind of multi-variable air conditioning unit of electric auxiliary heating, comprise the first indoor heat exchanger 1, second indoor heat exchanger 2, 3rd indoor heat exchanger 3, four-way change-over valve 4, outdoor heat exchanger 5, compressor 6, first electric expansion valve 7, second electric expansion valve 8, 3rd electric expansion valve 9, heating cabinet 10, electric heater 11, described compressor 6, four-way change-over valve 4, heating cabinet 10 successively closed loop connects, described four-way change-over valve 4, outdoor heat exchanger 5, first electric expansion valve 7, first indoor heat exchanger 1 successively closed loop connects.
The first described electric expansion valve 7, second electric expansion valve 8, the 3rd electric expansion valve 9 be connected in series the first indoor heat exchanger 1, second indoor heat exchanger 2, the 3rd indoor heat exchanger 3 respectively after be connected in parallel.
Described electric heater 11 is arranged in heating cabinet 10, and described electric heater 11 is connected with the control circuit of unit by wire.
The course of work of the present utility model is: after using the utility model, when outdoor temperature is very low, when needing temperature-compensating, electric heater 11 is energized, and the working medium flowing to heating cabinet 10 is heated, and liquid evaporates, what compressor 6 sucked is superheated steam, thus preventing liquid hammer and delivery temperature rising, heating capacity improves, and indoor heating effect rises.
The advantage of the present embodiment is, temperature-compensating, improves heating capacity, prevents liquid hammer; Reduce the size of gas-liquid separator, save the material manufactured, save space; Install simple, be easy to production operation.
