The equation I am considering is given by
\dfrac{\partial T}{\partial t}=\nabla cdot ( \nabla \lambda T))+ (\nabla \cdot v T)+H, T is the temperature, and H is the heat generation rate( source term). My question is whether H can be negative?

Yes, it can be negative, then one has a heat sink: e.g melting or evaporation act as heat sinks.

Yes, it can be negative, for example if you are using a peltier cooler

In energy conservation equation, the source term could be either positive or negative. If the magnitude of negative heat source exceeds the heat flow to the system, the temperature of the node will decrease.
