A coolant block of an air conditioner includes a block housing, and a first coolant chamber and a second coolant chamber formed in the block housing. The second coolant chamber is disposed adjacent to the first coolant chamber. The coolant block includes a first inflow flow path and a first discharge flow path formed in the block housing and fluidly connected to the first coolant chamber. The coolant block further includes a second inflow flow path and a second discharge flow path formed in the block housing and fluidly connected to the second coolant chamber. The coolant block also includes an expansion valve provided in the block housing and fluidly connected to the first discharge flow path, an expansion flow path formed in the block housing through which a coolant expanded in the expansion valve flows, and a connection flow path formed in the block housing that fluidly connects a compressor and a condenser.
