Abstract

An embodiment of the present invention provides a chiller. The water chiller includes a compressor connected in sequence, a refrigeration condenser and an evaporator, and a heat recovery condenser connected in parallel with the refrigeration condenser. The water chiller also includes a first electronic expansion valve arranged at the outlet of the refrigeration condenser and a second electronic expansion valve arranged at the outlet of the heat recovery condenser. The water chiller in the embodiment of the present invention can realize stepless adjustment according to the actual heat load demand, has small water temperature fluctuation and high comfort.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of air conditioning, and in particular to a water chiller. Background technique [0002] With the further development of refrigeration technology, the requirements for additional functions of chillers are also getting higher and higher. For heat recovery units, the current units are mainly divided into full heat recovery and partial heat recovery units. However, these two units can switch between cooling mode and heat recovery heat mode according to the customer's heat recovery demand, but they cannot be adjusted steplessly according to the heat load, so the temperature of the heat recovery water fluctuates greatly. figure 1 A schematic block diagram of an existing chiller is disclosed. Such as figure 1 As shown, an existing chiller 10 generally includes a compressor 11, a refrigeration condenser 12, a heat recovery condenser 13 connected in parallel with the refrigeration condenser ...
