The air conditioner mainly comprises an air conditioning system which is formed by compression, refrigeration and circulation steps, wherein a pipeline between a compressor and a condenser in the air conditioning system is connected with a refrigerating pressure test element in series, and the refrigerating pressure test element is connected with a control host machine in the air conditioning system; the air conditioning system internally comprises a refrigerating and heating four-way reversing valve which enables the rotation direction of a refrigerant to be circulating; and a pipeline between the compressor and an evaporator is also connected with a heating pressure test element in series, and the heating pressure test element is also connected with the control host machine. The pressure of the refrigerant of the air conditioning system is tested by a pressure test element, and the pressure test element can detect the pressure numerical value of the refrigerant in real time, so that the air conditioner can be ensured to be at a normal working state effectively.
Description
Technical field
What the present invention relates to is a kind of air-conditioner that has the refrigerant pressure checkout gear, belongs to the air-conditioner hormone and the field of the compression refrigeration circulatory system.
Background technology
The air-conditioner that adopts the compression refrigeration circulation to make is to utilize the circulation of cold-producing medium and the variation of the state of generation, realizes refrigeration or heats (utilizing reversal valve), and carry out indoor air conditioning, the technology of this respect has been quite ripe.But in actual use, people can find refrigeration or heating effect variation gradually, and its topmost reason is that cold-producing medium leaks, and causes air-conditioning refrigerant to reduce, and refrigerating efficiency reduces, and at this time, the way of taking has only one, i.e. refrigerant feeding immediately.Air-conditioning does not also have the ways and means of real-time monitoring refrigerant amount at present, is the pressure of measuring cold-producing medium when maintenance yet, to determine the amount of refrigerant feeding, if can monitor refrigerant amount in the air-conditioning in real time, can be and ensures that air-conditioning is in normal operating conditions.
Summary of the invention
The objective of the invention is to overcome the deficiency that prior art exists, and provide a kind of simple in structure, easy to install and use, can detect the pressure value of cold-producing medium in real time, be in the air-conditioner that has the refrigerant pressure checkout gear of normal operating conditions so that can effectively ensure air-conditioning.
The objective of the invention is to finish by following technical solution, it mainly comprises an air-conditioning system that is made of compression refrigeration circulation, be serially connected with a refrigerant pressure testing element on the pipeline in the described air-conditioning system between compressor and the condenser, and this refrigerant pressure testing element links to each other with main control system in the air-conditioning system.
Including one in the described air-conditioning system can make cold-producing medium turn to the cooling and warming four-way change-over valve of circulation, on the pipeline between described compressor and the evaporimeter, also be serially connected with one and heat the pressure test element, and this heats the pressure test element and also links to each other with described main control system.
Described main control system is formed for the control mainboard and the corresponding display screen of existing air-conditioner, refrigerant pressure wherein is installed on described control mainboard shows and warning device, and be connected in described display screen.
Described control mainboard is provided with the changes in temperature change-over switch corresponding with the cooling and warming four-way change-over valve, this changes in temperature change-over switch and described refrigerant pressure testing element and heat the signal that the pressure test element is connected on the control mainboard mutually and connect the corresponding configuration of switch.
The present invention has simple in structure, and is easy to install and use, can detect the pressure value of cold-producing medium in real time, so that can ensure effectively that air-conditioning is in characteristics such as normal operating conditions.
Description of drawings
Fig. 1 is the principle schematic of cooling cycle system of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is done detailed introduction: shown in Figure 1, the present invention mainly comprises an air-conditioning system that is made of compression refrigeration circulation, common described air-conditioning system is formed by connecting by pipeline by off-premises station and indoor set, wherein off-premises station includes a compressor 1, condenser 2, refrigerating capillary 3, four-way change-over valve 4 and connecting line 5, and described indoor set includes an evaporimeter and main control system.
Be serially connected with a refrigerant pressure testing element 6 on the pipeline in the described air-conditioning system between compressor 1 and the condenser 2, and this refrigerant pressure testing element 6 links to each other with main control system in the air-conditioning system.
Including one in the described air-conditioning system can make cold-producing medium turn to the cooling and warming four-way change-over valve 4 of circulation, by being installed in the refrigeration of control on the mainboard, heating switch and control described cooling and warming four-way change-over valve 4, flow the purpose that reaches refrigeration or heat with the commutation cycle that realizes cold-producing medium.
Also be serially connected with one on the pipeline between the evaporimeter in described compressor 1 and indoor set and heat pressure test element 7, and this heats pressure test element 7 and also links to each other with described main control system 8.
Described main control system is formed for the control mainboard and the corresponding display screen of existing air-conditioner, refrigerant pressure wherein is installed on described control mainboard shows and warning device, and be connected in described display screen.
Described control mainboard is provided with the changes in temperature change-over switch corresponding with cooling and warming four-way change-over valve 4, this changes in temperature change-over switch and described refrigerant pressure testing element 6 and heat the signal that pressure test element 7 is connected on the control mainboard mutually and connect the corresponding configuration of switch, and realization links.
When cold-producing medium reduces, pressure reduces when being not enough to operate as normal, control mainboard (main frame) will detect insufficient pressure, but Bao Jing with ∕ or demonstration, setting pressure is measured detecting element 6 or equipment in the refrigerating circuit of air-conditioning, when air-conditioning is set at the refrigeration attitude, refrigerant pressure testing element 6(equipment) detect hyperbaric environment, pressure signal is delivered to control mainboard (air-conditioner host), this control mainboard can detect pressure value in real time, when cold-producing medium reduces, pressure reduces when being not enough to operate as normal, the control mainboard will detect insufficient pressure, can report to the police or show, the prompting user adds cold-producing medium.
Implementing heating operation at air-conditioning is, heat pressure test element 7(equipment) the detection hyperbaric environment, pressure signal is delivered to control mainboard (air-conditioner host), the control mainboard can detect pressure value in real time, when the cold-producing medium minimizing, when the pressure reduction is not enough to operate as normal, the control mainboard will detect insufficient pressure, can report to the police or show, the prompting user adds cold-producing medium.
Also having shown in the figure: liquid stop valve 9, liquid reservoir 10, muffler 11, gas stop valve 12 and axial flow blower 13.
