Abstract

To accurately detect a condition of nonflowing usage fluid in a heat exchanger, a heat source unit includes a compressor configured to compress a refrigerant, a heater configured to heat the compressor, a first heat exchanger configured to exchange heat between the refrigerant and usage fluid, a first temperature sensor disposed on the first heat exchanger, a second temperature sensor disposed on the first heat exchanger in a position where heat amount to be received by heat radiation from the heater is different from the first temperature sensor, and a controller configured to prohibit start-up of the compressor based on difference between temperatures detected by the first temperature sensor and the second temperature sensor.
