Refrigerating and heating air-conditioner

The utility model relates to a heating and cooling air conditioner and proposes three conducting ways which are based on semiconductor cooling and heating technology. The utility model includes a thermoelectric heating and cooling chip, a hose, a fan, a temperature emission device, a temperature storage device, a liquid pump as well as a function control circuit. With liquid or gas or solid media used as thermal conductivity, the heat of the cooling surface or the heating surface of the thermoelectric heating and cooling chip is exchanged with the thermal conductivity according to the need of cooling or heating to achieve the heating and cooling air conditioner. Therefore, the air conditioner with small size and easy usage does not require Freon when cooling or heating, which is environmentally friendly and safe, and can achieve rapid cooling.
