Abstract

The present invention relates to a cooling system for cooling and heating the hidden heat produced in condensing the refrigerant compressed by a compressor, as well as a refrigerator using the system and a vending machine for selling canned drinks and other goods after heated or cooled. The present invention uses a plurality of pipelines in parallel connection to connect an expansive mechanism and an outdoor heat exchanger. In addition, when an accommodating chamber is cooled, the pathway of the refrigerant is provided with a pipeline with a drier; when the accommodating chamber is heated, the pathway of the refrigerant is provided with a pipeline besides the pipeline with a drier. Or, in the case of sharing the compressor, a three-way valve is used to make switch between a cooling system for cooling the accommodating chamber with drier in the pathway and a heating system for heating the accommodating chamber without drier in the pathway.

Description

technical field

[0001] The present invention relates to a cooling system for cooling and heating using latent heat generated when refrigerant compressed by a compressor is condensed, a refrigerator using the system, and a vending machine for heating or cooling products such as canned drinks. Background technique

[0002] In recent years, there has been an increasing demand for reduction in power consumption of refrigeration and heat storage equipment such as product showcases. For this reason, in order to reduce power consumption when heating with a heater, a technology has been proposed that switches the cooling system to a heat pump for heating in the same manner as in heating and cooling air conditioners. However, under refrigerated or frozen conditions such as product display cases, especially when the evaporating temperature is low, the water in the refrigerant freezes, which may clog the piping passage. Therefore, it is necessary to bring a desiccant composed of synth...

Examples

Embodiment 1

[0028] figure 1 It is a refrigerant circuit diagram of the cooling and heating system of Embodiment 1 of the present invention. The cooling and heating system of this embodiment basically consists of compressor 1, four-way valve (hereinafter referred to as valve) 2, accumulator 3, outdoor heat exchanger (hereinafter referred to as exchanger) 4, indoor heat exchanger (hereinafter referred to as exchanger) 5 and pipes connecting these in a ring. The refrigerator is composed of such a cooling and heating system and a storage chamber 6 in which an exchanger 5 is arranged. In other words, the accommodation chamber 6 is divided so that the exchanger 5 performs cooling or heating. When cooling the inside of the storage chamber 6 , the refrigerant discharged from the compressor 1 is supplied to the exchanger 5 from the exchanger 4 by switching the flow path through the valve 2 . Then, it flows back from the accumulator 3 to the compressor 1 through the valve 2 again. When heating...

Embodiment 2

[0081] Figure 7 It is a refrigerant circuit diagram of the cooling and heating system of Embodiment 2 of the present invention. The refrigerator of this embodiment has a storage room 6, a compressor 1, an evaporator 5B and a condenser 5A, an evaporator 4A and a condenser 4B, a three-way switching valve (hereinafter referred to as a valve) 2A, a two-way valve (hereinafter referred to as a valve) ) 11, 13 and dryer 14.
