Abstract

The invention discloses a kind of refrigeration system with the control of the highest evaporating pressure, include and circulated the compressor of connection, condenser and vaporizer by pipeline successively, being provided with expansion valve on connecting line between compressor and condenser, the temperature detector of expansion valve is arranged on the connecting line of vaporizer and compressor.The present invention arranges the expansion valve of band MOP function between the condenser and vaporizer of refrigeration system, by temperature detector sensing evaporator outlet temperature, pass to expansion valve executor, it is used for controlling the flow of cold-producing medium in refrigeration system circuit, thus control system evaporating pressure, make refrigeration system always work in rational range of operation, efficiently, safety, it is to avoid because vaporizer side air intake (or water inlet) temperature is too high and the situation that causes refrigeration system to be not normally functioning.

Description

There is the refrigeration system that the highest evaporating pressure controls
Technical field
The present invention relates to air-conditioning technical field, a kind of have the refrigeration system that the highest evaporating pressure controls.
Background technology
At the liquid low-temperature receiver unit that some all fresh air air-conditioning systems or confession liquid temp are higher, due to vaporizer air intake (or water inlet) Temperature is higher, easily causes evaporating temperature high.Evaporating temperature is too high to be exceeded after system particularly compressor allows range of operation, can lead Cause the damage of the low even compressor of running efficiency of system, make refrigeration system cisco unity malfunction.
Summary of the invention
It is an object of the invention to provide a kind of refrigeration system with the control of the highest evaporating pressure, in the condensation of refrigeration system The expansion valve of band MOP function is set between device and vaporizer, by temperature detector sensing evaporator outlet temperature, passes to expand Valve actuator control refrigeration system circuit refrigerant flow, thus control system evaporating pressure, make refrigeration system always work in Reasonably in range of operation.
Technical scheme is as follows:
A kind of have the refrigeration system that the highest evaporating pressure controls, and includes and is circulated the compressor of connection, cold by pipeline successively Condenser and vaporizer, it is characterised in that: expansion valve is installed on the connecting line between described compressor and condenser, described The temperature detector of expansion valve is arranged on the connecting line of described vaporizer and compressor.
Described has the refrigeration system that the highest evaporating pressure controls, it is characterised in that: described expansion valve uses band MOP The expansion valve of (control of the highest evaporating pressure) function.
The discharge-end temperature of temperature detector sensing evaporator also passes to expansion valve, is used for controlling refrigeration system circuit cold-producing medium Flow, thus control system evaporating pressure.
Beneficial effects of the present invention:
The present invention arranges the expansion valve of band MOP function between the condenser and vaporizer of refrigeration system, by temperature detector sense Know evaporator outlet temperature, pass to expansion valve executor, be used for controlling the flow of cold-producing medium in refrigeration system circuit, thus control System evaporating pressure processed, makes refrigeration system always work in rational range of operation, efficiently, safety, it is to avoid because evaporation Device side air intake (or water inlet) temperature is too high and the situation that causes refrigeration system to be not normally functioning.
Accompanying drawing explanation
Fig. 1 is present configuration schematic diagram.
Detailed description of the invention
Seeing Fig. 1, a kind of have the refrigeration system that the highest evaporating pressure controls, and includes and is circulated connection by pipeline successively Compressor 1, condenser 2 and vaporizer 4, the connecting line between compressor 1 and condenser 2 is provided with expansion valve 3, expand The temperature detector 5 of valve 3 is arranged on the connecting line of vaporizer 4 and compressor 1.
In the present invention, expansion valve 3 uses the highest evaporating pressure of band MOP(to control) expansion valve of function.
The discharge-end temperature of temperature detector 5 sensing evaporator 4 also passes to expansion valve 3, is used for controlling refrigeration system circuit system Cryogen flow, thus control system evaporating pressure.
Above example is not limited only to protection scope of the present invention, all basic thoughts based on the present invention and repair Change or change broadly fall into protection scope of the present invention.
