Abstract
An evaporator and a turbo chiller including the evaporator are provided. The evaporator may be a falling film evaporator which may distribute refrigerant to a heat pipe uniformly and which may also control two-phase flow by lowering dynamic pressures of gas refrigerant and liquid refrigerant, and separate the liquid refrigerant and the gas refrigerant from each other to enhance heat exchange efficiency.
Claims21
An evaporator, comprising:
- a distribution device comprising a first refrigerant inlet, a second refrigerant inlet and a plurality of flow channels;
- and
- a heat pipe configured to guide a flow of chilled water for heat exchange with refrigerant distributed by the distribution device, wherein the distribution device comprises:
- a first plate that receives refrigerant from the first and second refrigerant inlets, the first plate comprising a first plurality of flow channels that extend in a longitudinal direction of the distribution device;
- and
- a second plate that receives refrigerant from the first plate, the second plate comprising a second plurality of flow channels that extend in a width direction of the distribution device.
3 more elements
A chilling system, comprising:
- a compressor comprising an impeller compressing a refrigerant;
- a condenser performing heat exchange between refrigerant received from the compressor and chilled water;
- an evaporator performing heat exchange between the chilled water and refrigerant discharged from the condenser, the evaporator comprising a distribution device and a heat pipe in which the chilled water for heat exchange with refrigerant distributed by the distribution device flows;
- and
- an expansion valve provided between the condenser and the evaporator,
- wherein the distribution device comprises:
- a first plate comprising a first plurality of low channels extending in a longitudinal direction of the distribution device;
- and
- a second plate comprising a second plurality of flow channels extending a width direction of the distribution device to guide refrigerant received from the first plate therethrough.
6 more elements
A chilling system including an evaporator, the system comprising:
- a compressor comprising an impeller compressing a refrigerant;
- a condenser performing heat exchange between refrigerant received from the compressor and chilled water;
- and
- an expansion valve provided between the condenser and the evaporator, wherein the evaporator comprises:
- a separation device, comprising:
- a housing;
- a refrigerant inlet, at least one gas refrigerant outlet and a liquid refrigerant outlet provided at the housing;
- and
- a baffle plate provided in the housing, positioned between the liquid refrigerant outlet and the refrigerant inlet such that refrigerant drawn into the housing via the refrigerant inlet impinges on the baffle plate;
- a distribution device connected to the liquid refrigerant outlet of the separation device and configured to distribute liquid refrigerant received from the separation device sequentially in a longitudinal direction and a width direction of the distribution device;
- and
- a pipe configured to guide chilled water heat exchange with the liquid refrigerant distributed by the distribution device.
