PROBLEM TO BE SOLVED: To provide a temperature management system which includes temperature adjusting means and appropriately keeps temperature inside a greenhouse even if the outdoor temperature outside the greenhouse has dropped below a predetermined reference temperature.SOLUTION: A temperature management system 10 comprises: a heat pump-type air conditioner 22； a heater 28； an indoor temperature detection unit 32； an outdoor temperature detection unit 34； an operation panel 60 on which various conditions including a preset temperature inside the greenhouse are set； and a control unit 52. When the outdoor temperature outside the greenhouse 12 which is detected by the outdoor temperature detection unit 34 is below a predetermined outdoor air reference value, the control unit 52 adds an addition value corresponding to the outdoor temperature to a preset temperature set on the operation panel 60 to correct the preset temperature. Then, based on the preset temperature after the correction, the control unit controls operation of the air conditioner 22 and the heater 28, and raises a temperature inside the greenhouse 12 appropriately according to reduction of the outdoor temperature. Cost is reduced by operating the air conditioner 22 to the maximum.SELECTED DRAWING: Figure 1【課題】温度調節手段を備えた温度管理システムにおいて、ハウス外の外気温が所定の基準温度以下に低下しても、ハウス内温度を適切に保つ。【解決手段】温度管理システム１０は、ヒートポンプ式の空調機２２と加温器２８と、室内温度検出部３２と、外気温度検出部３４と、前記ハウス内の設定温度を含む各種条件を設定する操作パネル６０と、制御部５２を備えている。そして、前記制御部５２は、前記外気温度検出部３４により検出されたハウス１２外の外気温が、所定の外気基準値を下回ったときに、前記操作パネル６０で設定された設定温度に、前記外気温に応じた加算値を加えて前記設定温度を補正する。そして、当該補正後の設定温度に基づいて、前記空調機２２や加温器２８の運転を制御して、外気温の低下に応じてハウス１２内温度を適切に上げる。前記空調機２２を最大限稼働させることで、コストを削減する。【選択図】図１
