  • Patent number: 11554635
    Abstract: A heat circuit may include a controller configured to execute a first process and then a defrosting operation. The first process may be a process to execute a first air-heating operation and a heat storage operation simultaneously. The second process may be a process to execute a defrosting operation. The controller may be configured, in the first air-heating operation, to cause the radiator to heat a radiator passage and cause the air-heating apparatus to heat air using heat of a air-heating passage while circulating the heat medium in the radiator passage and the air-heating passage. The controller may be configured, in the heat storage operation, to circulate the heat medium in an electrical apparatus passage and a bypass passage. The controller may be configured, in the defrosting operation, to circulate the heat medium in the electrical apparatus passage and the radiator passage.
