Two sets of parameters are set in the temperature controller, and a user can switch the refrigerating system and the heating system by toggling the cold-heat change-over switch. When the cold-hot conversion switch is in a refrigeration gear, the internal heat exchanger is an evaporator, and the external heat exchanger is a condenser; when cold and hot change over switch is in the gear that heats, the temperature controller control four-way reversing valve changes the refrigerant flow direction in the system, and inside heat exchanger is the condenser, and outside heat exchanger is the evaporimeter, has made the show cupboard have the refrigeration and the function of heating. Meanwhile, refrigeration and heating are integrated into a set of system, so that the cost is greatly reduced, and the volume is reduced.
Description
Technical Field
The utility model relates to a commercial show cupboard especially relates to a cold and hot multifunctional cabinet system.
Background
With the improvement of the living standard, people have higher and higher requirements on food quality, safety, convenience, instantaneity and the like. In different seasons, foods sold in markets, supermarkets, convenience stores and the like are influenced by seasons, particularly in northern areas, and in addition, the requirements of people on the food fresh-keeping display environment are different. For example, in summer, people like to drink low-temperature refrigerated drinks, cool and relieve summer heat; in winter, people like to drink the hot water for heating and keeping warm. The cold and hot multifunctional cabinet can not only satisfy the show storage demand of the different temperatures of food, does not receive seasonal environment to influence the use moreover, has reduced electrical equipment, has promoted the utilization efficiency of equipment.
Disclosure of Invention
An object of the utility model is to provide a cold and hot multifunctional cabinet system with refrigeration and heating function.
In order to achieve the above purpose, the utility model can adopt the following technical proposal:
the utility model relates to a cold and hot multifunctional cabinet system, which comprises a unit system and a control system; the unit system comprises a compressor, a four-way reversing valve, a two-way throttling device, an external heat exchanger arranged outside a cabinet body and an internal heat exchanger arranged inside the cabinet body, wherein four interfaces of the four-way reversing valve are respectively communicated with an air inlet pipe of the compressor, an air outlet pipe of the compressor, the external heat exchanger and the internal heat exchanger, and the two-way throttling device is arranged on a pipeline between the external heat exchanger and the internal heat exchanger;
the control system comprises a temperature controller, a temperature sensor and a cold-hot change-over switch, wherein the signal output end of the cold-hot change-over switch is electrically connected with the signal input end of the temperature controller, the control output end of the temperature controller is in control connection with the control input end of the four-way reversing valve, and the signal input end of the temperature controller is electrically connected with the signal output end of the temperature sensor.
The utility model has the advantages of simple structure, practicality and convenience. Two sets of parameters are set in the temperature controller, and a user can switch the refrigerating system and the heating system by toggling the cold-heat change-over switch. When the cold-hot conversion switch is in a refrigeration gear, the internal heat exchanger is an evaporator, and the external heat exchanger is a condenser; when cold and hot change over switch is in the gear that heats, the temperature controller control four-way reversing valve changes the refrigerant flow direction in the system, and inside heat exchanger is the condenser, and outside heat exchanger is the evaporimeter, has made the show cupboard have the refrigeration and the function of heating. Meanwhile, refrigeration and heating are integrated into a set of system, so that the cost is greatly reduced, and the volume is reduced.
