Abstract
The present application concerns a climate control unit for controlling air temperature and/or humidity. Moreover, the present application concerns a system comprising such a climate control unit. The climate control unit according to the invention makes use of two refrigerant paths that share a common part in which a compressor and evaporator are arranged, and that each have a non-shared part. A reheat coil is provided in one of the non-shared parts. According to the invention, a respective expansion device is provided in both non-shared parts.
Claims22
A climate control unit for controlling air temperature and humidity, comprising:
- a reheat coil;
- a compressor;
- an evaporator having an output that is connected to an input of the compressor;
- a first expansion device arranged in a first refrigerant path, between an inlet of the climate control unit and an input of the evaporator, and configured to control a flow of the refrigerant in that path and to provide refrigerant directly to the evaporator;
- and
- a second expansion device arranged in a second refrigerant path, between the reheat coil and the input of the evaporator, and configured to control a flow of the refrigerant in the second refrigerant path and to provide refrigerant directly to the evaporator,
- wherein the first and second refrigerant paths share a common part and each have a respective individual part, and wherein the first and second expansion devices are arranged in the individual parts of the first and second refrigerant paths, respectively, and are configured to independently control the flow of refrigerant through the reheat coil and the flow of refrigerant directly entering the evaporator,
- wherein the first refrigerant path extends between an output of the compressor and an input of the evaporator through the inlet of the climate control unit, and wherein the second refrigerant path extends between the output of the compressor and the input of the evaporator through the reheat coil, and
- wherein the reheat coil is arranged inside the individual part of the second refrigerant path.
A climate control unit for controlling air temperature and humidity, comprising:
- a reheat coil;
- a compressor;
- an evaporator having an output that is connected to an input of the compressor, the climate control unit being coupled to a condenser for outputting thermal energy, wherein the climate control unit forms a refrigerant circuit together with the condenser;
- a first expansion device arranged in a first refrigerant path, between the condenser and an input of the evaporator, and configured to control a flow of the refrigerant in that path and to provide refrigerant directly to the evaporator;
- and
- a second expansion device arranged in a second refrigerant path, between the reheat coil and the input of the evaporator, and configured to control a flow of the refrigerant in the second refrigerant path and to provide refrigerant directly to the evaporator,
- wherein the first and second refrigerant paths share a common part and each have a respective individual part, and wherein the first and second expansion devices are arranged in the individual parts of the first and second refrigerant paths, respectively, and are configured to independently control the flow of refrigerant through the reheat coil and the flow of refrigerant directly entering the evaporator,
- wherein the first refrigerant path comprises a pathway defined between an output of the compressor and an input of the evaporator through the condenser, and wherein the second refrigerant path comprises a pathway defined between the output of the compressor and the input of the evaporator through the reheat coil, and
- wherein the reheat coil is arranged inside the individual part of the second refrigerant path.
The climate control unit according to 16, wherein the second refrigerant path extends between the output of the compressor and the input of the evaporator through the condenser and through the reheat coil in that order.
