PURPOSE: A valve block and an air conditioner therewith are provided to improve coil properties by connecting components using the valve block and to improve productivity without a welding work. CONSTITUTION: An air conditioner with a valve block comprises a compressor(50), an outdoor unit(65), an indoor unit(70), multiple pipes, opening and closing valves, a cooling expansion valve, a heating expansion valve(75), an oil separator(60), and an accumulator(45). The outdoor unit evaporates or condenses a refrigerant using external air and heat-exchanging. The pipes form a refrigerant flow line. The opening and closing valves are installed in the pipes. The cooling expansion valve is installed in the pipe flowing the refrigerant from the outdoor unit to the indoor unit. The heating expansion valve is installed in the pipe flowing the refrigerant from the indoor unit to the outdoor unit. The oil separator divides the refrigerant mixed with oil. The accumulator divides a gas refrigerant and a liquid refrigerant.
