Description

[Detailed Description of the Invention] The present invention relates to the configuration of a cooling and heating device that obtains a cooling liquid and a heating liquid at the same time, and in particular, cooling and heating using the same refrigerant device.

Conventionally, this type of cooling and heating apparatus has used a refrigerant cycle evaporator for cooling and an electric heater for heating in order to obtain cooling liquid and heating liquid at the same time.

As a result, the capacity of the electric heater becomes large, which is uneconomical, and the refrigerant cycle is not used effectively, resulting in wasted energy.

The present invention was developed in view of the above-mentioned points, and will be described below with reference to the drawings, with an embodiment being a water cooler/heater.

1 is a cold/hot water machine equipped with a refrigerant cycle device consisting of a refrigerant compressor 2, a condenser 3, a radiator 4, a dryer 5, a capillary tube 6, an evaporator 7, a heat absorber 8, a gas-liquid separator 9, etc. In the main body,
The condenser 3 and the radiator 4 are piped in parallel via a first switching valve 10, and the refrigerant from the refrigerant compressor 2 is switched to one of them by the first switching valve 10 to flow.

The evaporator 7 and the heat absorber 8 are piped in parallel via a second switching valve 11, and the refrigerant that has passed through the capillary tube 6 is switched to one of the two by the second switching valve 11.

The condenser 3 and the evaporator 7 directly or indirectly interact with a liquid such as water or drinking water injected into a heating tank 12 and a cooling tank 13 that are formed substantially independently of each other in the main body 1. They are arranged in a heat exchange relationship.

The heat radiator 4 and the heat absorber 8 are connected to the blower 14 as necessary.
15, which is driven when the refrigerant is flowing to promote heat dissipation and visual acuity.

The first switching valve 10 is normally set to flow the refrigerant from the refrigerant compressor 2 to the condenser 3, and
When the inside of the refrigerant 2 is heated to a predetermined temperature, the temperature sensor 16 is energized to switch the refrigerant flow direction to the radiator 4 side.

The second switching valve 11 is set so that the refrigerant that has passed through the condenser 3 or the radiator 4 normally flows to the evaporator 7 side, and when the inside of the cooling tank 13 is cooled to a predetermined temperature, the temperature changes. By energizing the sensor 17, the refrigerant flow direction is switched to the heat absorber 8 side.

The operation of the refrigerant compressor 2 is stopped when the two openings 10 and 11 are switched, that is, when the two tanks 12 and 13 reach a predetermined temperature.

18 and 19 are faucets communicating with both the tanks 12 and 13, respectively.

Since the present invention is constructed as described above, the condenser and evaporator of the refrigerant cycle can be effectively used, and even if an electric heater is required, its capacity may be small, resulting in a large energy saving effect.

Moreover, even if one of the cold and hot tanks reaches a predetermined temperature, the other tank continues to cool or heat, and the refrigerant that has reached the predetermined temperature is not passed through, so that neither overcooling nor overheating occurs, and both tanks are kept cool. It can be cooled and heated to a predetermined temperature quickly and satisfactorily.
