1. Cooling equipment comprising: a storage chamber that stores storage goods;a first latent heat storage member that is inside the storage chamber and includes at least a first latent heat storage material that is reversibly phase-transited between a solid phase and a liquid phase;a second latent heat storage member that is inside the storage chamber and includes at least a second latent heat storage material that is reversibly phase-transited between the solid phase and the liquid phase;a sensor that is in contact with or included inside the second latent heat storage member and detects a state of the second latent heat storage member;a cooling mechanism that cools the inside of the storage chamber; andcontrol circuitry that controls the cooling mechanism, based on a state of the second latent heat storage member, whereinthe second latent heat storage member is phase-transited earlier than the first latent heat storage member, anda thickness of the second latent heat storage member is thinner than a thickness of the first latent heat storage member. 2. The cooling equipment according to claim 1, wherein during cooling of the storage chamber, at least a portion of the second latent heat storage member completes phase-transition and freezes earlier than the first latent heat storage member, andwhile cold is radiating from the storage chamber, at least a portion of the second latent heat storage member completes the phase-transition and melts earlier than the first latent heat storage member. 3. The cooling equipment according to claim 1, wherein the state includes any one of a temperature, a volumetric change, a mechanical strength, and optical characteristics. 4. The cooling equipment according to claim 1, wherein the cooling mechanism includes any one of a compressor, an opening of a cold air port or a vent hole, and a cooling fan. 5. The cooling equipment according to claim 1, wherein a latent heat amount in a thickness direction of at least a portion of the second latent heat storage member is smaller than a latent heat amount in a thickness direction of at least a portion of the first latent heat storage member. 6. The cooling equipment according to claim 1, wherein the sensor is disposed in a section where the latent heat amount in the thickness direction of the second latent heat storage member is smaller than the maximum value of the latent heat amount in the thickness direction of the first latent heat storage member. 7. The cooling equipment according to claim 1, wherein the second latent heat storage member includes a recess, andthe sensor detects a state of the recess. 8. The cooling equipment according to claim 1, further comprising: a plate-shaped member that is included in the second latent heat storage member and has a thermal conductivity higher than a thermal conductivity of the second latent heat storage member, wherein the sensor is arranged in contact with the plate-shaped member. 9. The cooling equipment according to claim 1, wherein the second latent heat storage member has heat conductive filler or particulates having no latent heat in a control temperature range. 10. The cooling equipment according to claim 1, wherein the first latent heat storage member includes a container body that seals the first latent heat storage material, and the second latent heat storage member includes a container body that seals the second latent heat storage material. 11. The cooling equipment according to claim 1, wherein a material included in the first latent heat storage material is a same material included in the second latent heat storage material. 12. The cooling equipment according to claim 1, wherein the second latent heat storage material is arranged at a position where cold air blowing into the storage chamber is likely to hit relatively and near a corner inside the storage chamber.
