A food service table (10) is provided which includes separate heating and cooling systems enclosed within a housing (12) which may be selectively activated to heat or to cool food displayed and served on the table. Substantially all of the upper surface (13) of the housing (12) includes a food service area (14) in which is mounted a food service pan (24). Heating elements (26) and cooling coils (42) mounted on the pan (24) heat or cool foods displayed in the pan. The cooling system includes accumulator means (34) positioned at the lowest level of the cooling system for receiving and collecting refrigerant fluid upon activation of the heating system. Control means are provided to control the expansion and flow of refrigerant fluid during operation of the heating system.
