Abstract
A plant growth chamber has an interior region, and a heat exchanger. The heat exchanger has a fluid volume separated from the interior region, and a solid state heat pump configured to transfer heat between the fluid volume and the interior region for heating and/or cooling the interior region.
Claims (23)
1. A plant growth chamber comprising : an interior region; and a heat exchanger comprising : a fluid volume separated from the interior region; and a solid state heat pump configured to transfer heat between the fluid volume and the interior region for heating and/or cooling the interior region.
2. The plant growth chamber of claim 1, wherein the plant growth chamber further comprises: a gas inlet configured to deliver gas to the interior region; and a gas inlet heat exchanger arranged adjacent to the gas inlet, the gas inlet heat exchanger comprising a solid state heat pump configured to transfer heat between the inlet gas and a fluid volume of the gas inlet heat exchanger for heating and/or cooling the inlet gas.
3. The plant growth chamber of claim 2, further comprising a humidifier adjacent to the gas inlet, wherein the humidifier in configured to increase the humidity of the inlet gas to a desired humidity.
4. The plant growth chamber of either of claims 2 or 3, further comprising a dehumidifier adjacent to the gas inlet, wherein the dehumidifier is configured to reduce the humidity of the inlet gas to a desired humidity.
5. The plant growth chamber of claim 4, wherein : the dehumidifier is configured to control the gas inlet heat exchanger to cool the inlet gas to condense water vapour from the inlet gas to generate inlet gas of a desired humidity; and the gas inlet heat exchanger is configured to recover the heat energy extracted when cooling the inlet gas during dehumidification.
6.

14. The plant growth chamber of any of claims 11 to 12, wherein the second thermally- conductive wall is in thermal contact with either: a region adjacent a gas inlet configured to deliver gas to the interior region, wherein the second thermally-conductive wall is configured to transfer heat between the fluid volume and the inlet gas; or a region adjacent a gas outlet to remove gas from the interior region, wherein the second thermally-conductive wall is configured to recover heat energy from the outlet gas.
15. The plant growth chamber of any preceding claim, further comprising one or more thermal bridges which thermally couple first and second thermally-conductive plates.
16. The plant growth chamber of any preceding claim, wherein the fluid volume comprises a fluid inlet and a fluid outlet.
17. The plant growth chamber of claim 16, wherein the fluid inlet is configured to draw fluid from outside the plant growth chamber into the fluid volume and the fluid outlet is configured to remove fluid from the volume to a region outside the plant growth chamber.
18. The plant growth chamber of claim 17, wherein the solid state heat pump is configured to transfer heat energy between the fluid and the interior region.
19. The plant growth chamber of either of claims 17 or 18, wherein the fluid is a gas or a liquid.
20. The plant growth chamber of any preceding claim, further comprising one or more lights for providing light to the plant growth region, wherein the one or more lights are thermally coupled to the heat exchanger.
21. The plant growth chamber of any preceding claim, wherein the solid state heat pump is a thermoelectric heat pump.
22. The plant growth chamber of any preceding claim, further comprising a control loop configured to control the solid state heat pump in order to achieve a desired temperature in a plant growth region.
