Abstract

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

Description

There is the refrigeration system of highest evaporating pressure control
Technical field
This utility model is related to air-conditioning technical field, specifically a kind of refrigeration system with the control of highest evaporating pressure.
Background technology
In some all fresh air air-conditioning systems or for the higher liquid low-temperature receiver unit of liquid temp, 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 that running efficiency of system is low or even the damage of compressor, make refrigeration system cisco unity malfunction.
Utility model content
The purpose of this utility model is to provide a kind of refrigeration system with the control of highest evaporating pressure, in refrigeration system Between condenser and vaporizer, the expansion valve with MOP function is set, by temperature detector sensing evaporator outlet temperature, passes to Expand valve actuator and control refrigeration system circuit refrigerant flow, thus control system evaporating pressure, make refrigeration system work all the time Make in rational range of operation.
The technical solution of the utility model is as follows:
A kind of refrigeration system with the control of highest evaporating pressure, includes the compression circulating connection by pipeline successively Machine, condenser and vaporizer it is characterised in that:On connecting line between described compressor and condenser, expansion is installed Valve, the temperature detector of described expansion valve is arranged on described vaporizer and the connecting line of compressor.
The described refrigeration system with the control of highest evaporating pressure it is characterised in that:Described expansion valve is using band MOP (Highest evaporating pressure controls)The expansion valve of function.
The discharge-end temperature of temperature detector sensing evaporator simultaneously passes to expansion valve, for controlling refrigeration system circuit cold-producing medium Flow, thus control system evaporating pressure.
The beneficial effects of the utility model:
This utility model arranges the expansion valve with MOP function between the condenser and vaporizer of refrigeration system, passes through Temperature detector sensing evaporator outlet temperature, passes to expansion valve actuator, for controlling the stream of cold-producing medium in refrigeration system circuit Amount, thus control system evaporating pressure, makes refrigeration system always work in rational range of operation, efficient, safety, it is to avoid Because vaporizer side air intake(Or water inlet)The situation that temperature is too high and leads to refrigeration system to be not normally functioning.
Brief description
Fig. 1 is this utility model structural representation.
Specific embodiment
Referring to Fig. 1, a kind of refrigeration system with the control of highest evaporating pressure, include and connection is circulated successively by pipeline Compressor 1, condenser 2 and vaporizer 4, the connecting line between compressor 1 and condenser 2 is provided with expansion valve 3, expands The temperature detector 5 of valve 3 is arranged on vaporizer 4 and the connecting line of compressor 1.
In this utility model, expansion valve 3 is using band MOP(Highest evaporating pressure controls)The expansion valve of function.
The discharge-end temperature of temperature detector 5 sensing evaporator 4 simultaneously passes to expansion valve 3, for controlling refrigeration system circuit system Cryogen flow, thus control system evaporating pressure.
Above example is not limited only to protection domain of the present utility model, all based on basic thought of the present utility model And modify or change broadly fall into protection domain of the present utility model.
