Air conditioning system with heat pump section and separate heat source section |
摘要 |
An air conditioning system includes a heat pump section performing indoor air-warming by using a vapor-compression refrigeration cycle, a separate heat source section performing indoor air-warming by using a heat source separate from the heat pump section, and a control unit configured to control actions of the heat pump section and the separate heat source section. When an operation is switched from a separate heat source air-warming operation to a heat pump air-warming operation, the control unit starts the heat pump air-warming operation while the separate heat source air-warming operation is continued, and after an overlapping air-warming ending condition is met, the control unit ends the separate heat source air-warming operation. The overlapping air-warming ending condition is that a temperature difference resulting from subtracting a target indoor temperature from an indoor temperature is equal to or greater than an overlapping air-warming ending air temperature difference. |

1. An air conditioning system, comprising:
a heat pump section arranged and configured to perform indoor air-warming by using a vapor-compression refrigeration cycle; a separate heat source section arranged and configured to perform indoor air-warming by using a heat source separate from the heat pump section; and a control unit configured to control actions of the heat pump section and the separate heat source section, when an operation is switched from a separate heat source air-warming operation performing indoor air-warming by using the separate heat source section to a heat pump air-warming operation performing indoor air-warming by using the heat pump section, the control unit starting the heat pump air-warming operation while the separate heat source air-warming operation is continued, and after an overlapping air-warming ending condition is met, the control unit ending the separate heat source air-warming operation, and the overlapping air-warming ending condition being that a temperature difference resulting from subtracting a target indoor temperature from an indoor temperature is equal to or greater than an overlapping air-warming ending air temperature difference. |
