Abstract
A ground source heat pump integrated controller includes a main module that has pre-integrated multiple main machines, pumps and valves according to the rated load of the main module, and a number of extended modules that have pre-integrated multiple main machines, pumps and valves according to a rated load of the extended modules. The main module and extended modules both are provided with a plurality of analog contacts and digital contacts, and the extended modules are connected, via the analog and digital contacts, to the main module according to the rated load of the ground source heat pump system. The advantage of the ground source heat pump integrated controller lies in that after system load is calculated according to floor area, multiple extended modules are connected to one main module, which increases the capacity of the main module and thus meets the requirement of system load.
